how to install a second battery.

[iivanTV]

hey bro nice vid, i have a kinetik aswell but i wanna take my buddys kinetik off his hands there both no more than a year old. will one drain the other? there both diffrent sizes

[PeytonKalil881]

Do you have an upgraded alternator? Cause if not wouldn't the little stock alternator fry out with those two battery's on it?

[SubZeroSkyLine]

@PeytonKalil881 a stock alternator can handle maybe 2000 RMS of power ( the average 120 amp alternator )

[M0NEYM0VES]

Really good info!

[mattman20132]

also, is it a good idea to get the same 2 batteries?

[mattman20132]

can you ground stuff in the same place?

[BDAWKTOMAHAWK]

so just ground the 2nd battery then get one power wire with a fuse on it as if it was for an amp to the original battery and then another power wire from 2nd battery with another fuse to the amp? and if i need an 80 amp fuse for my amp would i put and 80 amp fuse on both power wires or just a 40 on each one or would either way work?

[lntervention]

Okay. front Pos to rear Pos. two fuses inbetween front and rear. then you ground your rear battery and thats that ? then you put a fuse from your rear battery to your amp. do you need to ground your amp also ? or can you run it to the negative term on the rear battery ? i just got an optima yellow top and im planning on running my 2000 watt amp and 15 off it. Please help. thank ya

[DrEwBaBy625]

@lntervention yup pos to pos and grnd the pattern to frame then pos to amp then ground the amp either to the frame or to the battery either will work

[Gunnedslingers1]

so u have to connect both negative terminals of the two batteries to have them operate correctely?? or can you just ground the second battery and connect just the postive terminals of the two batteries?? please help. thanks

[DrEwBaBy625]

@Gunnedslingers1 connect the 2 positives then ground the second to the frame

[coled7lan]

why do people use capacitors?? i dont see the point. and the point of cross overs

[DrEwBaBy625]

@coled7lan yeah caps are pointless. but crossovers save your tweeters. tweeters are meant for high frequencies only and any bass can blow them and distort them the crossover cuts out the lows to protect your tweeters.

[BENAY54]

Great info..

[pussytastegood1]

@carlos415 caps do nothing unless the alternator is putting out more Amps then you system is drawing, I would just get a high output alternator but if you can't get one for the car then a second battery is the way to go

[liftedJ33P]

So in other words you can compare the fact of one of the battery's being dead to Two people on a tandem bicycle and only one of them is peddling, eventually the guy peddling will over work him self and completely just die.haha i love my brain

[zechariahtheking]

would it be alright if I ground the second battery in the back instead of running it to the main battery under the hood or would it be better if I ran it to the main battery juz like what i'ma do with the positive 0 guage wire

[carlos415]

hey i want to install a 2nd batt but people say i should get a cap better,,what do u think? i have 2 kicker l7 12" and a kicker 2500.1...stock alt and stock front batt...should i get a kinetik 2400? or a cap? please repond

[88DJdan]

so when this 2nd battery is installed....is it possible(asking) for this 2nd battery to start your vehicle engine even though you disconnect the 1st battery terminals?

[tatsumaru12345]

How big of fuses are ya running in between batterys?

[Mitchumthegreat]

how do u know what size fuses to put on the wire between the two batteries?

[kakhoofd456]

i have a question if you hook up a second battery to you factory battery then it's gonna dubble the amps would it blow al your cars fuses??

[JATnz16]

on the second battery does it recharge it self like the first while the car is running?????

[HolyShitNewsTV]

How do you know how many amps your fuse has to be for the battery?

[sparky3489]

The thing is, people get confused in the real purpose of a cap. A cap is not used to, cure or prevent dimming lights, change the way the system sounds or save the battery/alternator (all are misconceptions).

To undertsand the purpose you need to understand how they work.

A cap does it's best to keep the voltage at a certain level, but if the voltage changes so will the cap voltage. The cap just makes the change smoother.

[Belyea09]

do you happen to know how many amps an isolator should have to run music with my car off if i install a second battery?

[facestomp88]

I'm planning on doing this soon as I get the extra money. I just got an amp in my car and I'm having some issues with the lights dimming, I will also be doing the big 3 upgrade at the same time as well and will be getting a battery isolator. The only question I have is what size fuse do you recommend using on each battery to fuse them in case of a short so there is no problem?

[mazilusanel]

it's any problem when the batteries have different amperages..( 60 Ah with 100 Ah ), 12 volt both..pls answer :p

[Angelboy863]

quick question, does having two batteries put alot of stress on your alternator and do you think having an isolator and relay will/would change that? thanks

[DrEwBaBy625]

@Angelboy863 if both batteries are kept charged it shouldn't put too much more strain on your alternator. having an isolator might help if you plan on running your system with the car off because then you only have one battery that is charging off the other battery and the alternator instead of 2 dead batteries

[sheehan360]

is that a mofo 12? i was just lookin those up before this... im getting 2 of them!!! rock on and thanks for the tips! power acoustik FTW!

[DrEwBaBy625]

@sheehan360 its a mofo 15

[abdi862]

science lesson right here!!

[pcgamergod]

i want to put another battery in the back of my car, I bought a optima yellow top battery, but in the front there is a normal acid battery. would that make a problem? (the acid battery draining the yellow top one???) please help

[DrEwBaBy625]

@pcgamergod not sure if that would create any problems, i would contact optima and ask them.

[fingerboy18]

@pcgamergod When you wire 2 batteries in parallel, the voltage will equalize due to potential differences and the internal resistances. Your batteries may cause each-other to heat up. The best bet is to get identical batteries. You may want to just use a capacitor. Capacitors have very low "ESR", equivalent series resistance. This means that they can provide a huge amount of current very quickly. Batteries can't due to their fairly large resistance.

[pcgamergod]

@fingerboy18 ok thanks for the comment! :-)

i'm really having a hard time to find some good batteries here in europe for car audio ...

planning to get myself 2 kinetics ;-) that should work ^^

thanks again!

[audiole562]

@pcgamergod I say you take a look at xstatic bat caps for car audio. good pricing and great second batteries for and audio setup

[6476Mike]

what happens if you wire the batteries in series rather than in parallel - is it the same thing or will you have 24 volts instead of 12???

[realskater17]

@6476Mike if u wire batteries in series it will start a fire or cause explosion

[DrEwBaBy625]

@6476Mike if you wire 2 batts in series yes you will get 24v which may cause some of the electronics in your car to catch fire. and the more batteries you wire together the higher the voltage will get so if you wire 5 12v batts in series you will get 60v.

[xConway22x]

drewbaby does your truck have the stock alt?

[ThatsGlory]

so if i had a 1,500 rms amp would i need a second battery ?

[DrEwBaBy625]

@ThatsGlory 1500 rms amp would be pulling about 125A at 12v. most cars when running are like 13-14v but even at 14v you would be pulling 108A so unless you have a big alt that could handle all that i would get a sec or even a 3rd battery

[strtslpr]

no isolator?

[FluentSarcasm1]

by  the car being off u mean on "accesory" ? and when the car is running can ur alternator handle it?

[bestpcguy]

Should I use a battery isolator so the alternator will charge both batteries? I'm afraid when my battery in the trunk drains in will drain my main battery.

[alll626]

will my altenator keep it charged? 2006 hyundai 1200w rms system

[wow1022]

extra battery is cheaper and more effective than a capacitor

[FluentSarcasm1]

so i have an amp already hooked up ok? can i just use the wires that are hooked to it and just run them into a new battery? plz help

[MoreLikeCappuccino]

@FluentSarcasm1 yeah just add anthor fuse to the end of your amp wire just like he said

[sikvibration]

@robertismad thanks a heap mman fusing is something iv been tryin to learn more about

[icanbelouder]

@DrEwBaBy625 Can i ground my amp to my back seat and then ground my second battery to the front seat

[kingwayne87]

if i have two amps would i have a fuse for both

[DrEwBaBy625]

@kingwayne87 depends if you have seperate wires run for each

[lolan92]

@DrEwBaBy625 If you have the batteries wired in parallel won't that put a lot more strain on the alternator since it's powering pretty much twice as much batteries?

[Po0rEmerica]

@lolan92 Ya but not as much as people think it does.

[lolan92]

@Po0rEmerica how much extra drain would it take? like one alternator without a system should run at around 14 amps what would one with a system and two batteries run at?

[rbnsandoval]

Good video.

[BigConey93]

ey bro when you put a second battery can you hook up the 0 gauge from the battery to a distrabution block and run 4 gauge to the amps?

[GypsyRider]

I was just wondering where you picked up the in-line fuses? trying to find some for a multi-battery car system for a mobile Radio Shack

[sikvibration]

hey man olny thing i need to know is what amp fuses do i use the alternator im gettin is 250amp and i got 3 batteries goin in the trunk

[robertismad]

@sikvibration 300amp fuses you want as much power as you can get

[1kickass]

so i guess i'll get a capacitor then unless i feel like buying two new batteries then... good video very informative

[mnmsoccer]

so basically you can just put them in a series or w.e u said and u wudnt have to do anything else except fuses? srry for the dumbass question

[kwyjibosponge]

1:20 - 1:30 I dont think you have a clue what your talking about

[BigConey93]

@kwyjibosponge he makes perfect sense bro

[JuanPapaNicolao]

Good vid

[MuzikVideoz]

@fennygolf don't act like u kno shit, I did sum research and looked at the smh forums and ask steave meade & EXO, they both said u shud for the same reasons he did. If u don't kno them then don't act big, itz not no filing wiring skill, itz protecting ur system and car from harm. If ur so good at wiring, run no fuse and record it and show us wut happens.

[MuzikVideoz]

k thx, also do i need to do 1/0 gauge wires for the battery? or 4 gauges are fine? i heard running 4 gauge batt to batt isnt safe. lmk thx again.

[fennygolf]

be sure that those fuses are high 2 60 amp ANL fuses would be fine is the fuse that goes from batt to amp u need to have a high rating

[DrEwBaBy625]

@fennygolf the size of the fuse depends on the wire size. if you put a 200A fuse on some 8 gauge and over draw it the wire will catch fire before the fuse pops

[fennygolf]

@DrEwBaBy625 with 0/1 cable 2 90s would be fine im putting 2 fuses in my car also 1 between the alt and battery and 1 between the battery and amp if u trust your wiring skills then u wouldnt have to double fuse your wire not judging your skills or anyhting

[broncobass22]

@DrEwBaBy625 hey um i hooking up a kinetik hc 800 and am using 4 gauge wire what 2 fuses do i use and i lisen 2 my music when my truck is turned off some times so should i buy a isolater and if so how many amps i can get a 500 amp for 60 is that 2 much or do i need a bigger on or a smaller one my amp is 1800w but my subs to gether a 2500w and im ussing a 300w for mids and highs

[MuzikVideoz]

can i ground the 2nd battery in the back? or does the neg terminal on both batteries have to be connected?

[DrEwBaBy625]

@MuzikVideoz you can ground it in the back just make sure its a good solid ground to the frame

[TheHiddenNazis]

"what type of external battery do you recommend for a lanzar 1233d subwoofer 6000w peak 3000w rms? i also have a 6000 watt amp.

i already have one of these subs hooked up and it can barely handle the power on that one sub so i need another battery any ideas on what battery at a reasonable price?"

[cplhornby]

are these connected in series or parallel?

[jrnelson21]

what kind of alternator do you have?

[DrEwBaBy625]

@jrnelson21 stock. i think its a 70 amp? not a bad alt tho keeps me at 14v

[JuanPapaNicolao]

@DrEwBaBy625 for some reason 70 amp alt sucks in my car

[sorrowdragon]

sounds like you need to get out more and exercise... you seem out of breath from doing nothing but holding a camera and talking...

[DrEwBaBy625]

@sorrowdragon yeah sometimes that happens when you have a cold and its like 10 degrees out

[TheRuthlessBastards]

if i were to use two batterys on a 2 1000 watt amps could i use 4 guage wire? or would it have to be 0 guage?

[DrEwBaBy625]

@TheRuthlessBastards i would use bigger than 4 gauge i have 2 gauge and that works fine but the bigger the better

[TheRuthlessBastards]

@DrEwBaBy625 alright thanks, i got one more questions im getting mixed opimions about this but if i wanted to run 2 1000 watt amps would i need a new battery, compacitor, or what would be easiest because i would think there would begin to be voltage drop.

[iluvithaha]

hey check out my problem vid im gonna buy the 800 jw if my hyundai can fit it and if its ok to use as a regular car batt and ditch my old one?

[anaelisem2000]

Nice video.

One question, if I have two battery, still do I need to upgrade alternator? My Sub is 1000 Rms Earthquake 15 inch.

[DrEwBaBy625]

@anaelisem2000 depends on you voltage drop. if your still getting a lot of drop yeah you should but if not then should be fine. i didnt upgrade mine and its all doing fine

[EvaXdelo]

THANK YOU SOOO MUCH

i wondoring if the secoand battery will effect alternator ?

what do i need upgrade it to have secoand battery ?

i hope find the answer

[R32Viper]

What about the cable going to the amp from the second battery does it needs a fuse as well?

[DrEwBaBy625]

@R32Viper yes. with in 12" of the battery

[jvsnopro]

great vids man!! very very helpful!! thnks!!

[jregamey]

Ya today i just hooked up dual batteries. I used a relay or aka solenoid, at lordco was only 25 bucks. So I have my entire stereo plugged into the rear battery, also down the lines i wanna run fog lamps or a computer ill run it off the rear battery.

[dragon8223]

so both the ppositive and the negitive from the first battery need to hook to the back battery?

[DrEwBaBy625]

@dragon8223 well positive to positive negative to ground

[midnightnavyz28]

@DrEwBaBy625

the best ground would be the battery

[zechariahtheking]

front to the positive charge on the alternator so it will charge that batttery to so than it will be charging both batteries

[tonysalsa100]

@zechariahtheking very nice well said thanks you the man!!

[zechariahtheking]

@tonysalsa100 no problem bro anytime

[zechariahtheking]

could you also ground your wire from the amp to the 2nd battery in the back and I know that the power wire goes from the positive terminal in the back to the battery in the front and the power wire from your amplifier also go 2 the positive terminal on the 2nd battery in the back... But could you add a 3rd power wire from the positive terminal on the second battery in the back to the alternator positve charge so it will charge the battery in the back and another one from the battery in the

[deathofwynter]

where is your battery isolator??? I was told you have to have one when you put a second battery in for car audio.

[DrEwBaBy625]

@deathofwynter only thing you need an isolator for is if you like to listen to music with your car off. the isolator allows you to kill one battery and keep the other one charged that way you can stillstart the car off the good battery then after its started the isolator allows the dead battery to be charged

[luisin321123]

ok my friend if my amplfier is 5000w but in characteristics say 2x60 amps. my question is can conecet 3 fuses of 200a for de firts baterry to second baterry and also to de second battery to my amplifier ? cus my total rms is 2000w rms

[DrEwBaBy625]

@luisin321123 your fuse size has nothing to do with the size of your amp. you want to rate the fuse with your wire size. so you need to decide what size wire your going to go with. an amp that big i would go with at least 2 gauge if not bigger for 2 gauge you need a 150A fuse if you go with 1/0gauge wire its a 200A fuse

[luisin321123]

@DrEwBaBy625 aa ok so I decided use 0 gauge wire thanks my friend. If my alternator has 130A is necessary put another of 200A for my 2000rms or can I use this 130A?

[DrEwBaBy625]

@luisin321123 you should be fine with the stock alt ive been running the stock alt on mine and havent had any problems.

[luisin321123]

@DrEwBaBy625 ok then I will install my big 3 with 0 gauge wire to my alternator 130A, I will also install a second battery. my last question. is that I have to put a 250A fuse on my alternator to my battery? and 200A fuse between the 2 batteries? I really appreciate your help.

[DrEwBaBy625]

@luisin321123 if your running all 0 gauge then they all have to be 200A . the fuse is what protects your wire so if you put in too big of a fuse and theres a short the wire would burn up and catch fire before the fuse pops

[sfvirgo]

@DrEwBaBy625

so my alternator is 90 amps, i did my big 3 in o gauge... do i still use a 200 amp fuse? if it shorts wont it fry any way cuz the fuze is too big?

[xrunebowx]

say i have a car with a 5000w amp, and im looking to installing another battery for more power to my 15s, would this way help for getting more power and not draining my car battery as fast?

[DrEwBaBy625]

@xrunebowx it sure would.

[xrunebowx]

say i have a car with a 5000w amp, and im looking to installing another battery for more power to my 15s, would this way help for getting more power and not draining my car battery as fast?

[ihaec18]

simple and to the point !!!!

THANKS DUDE

[zechariahtheking]

so the second battery power wire connects to the one you have under the hood and than you take the ground wire from the second battery and ground it to the frame of the car? But than where will you connect the power wire from the amplifer

[DrEwBaBy625]

@zechariahtheking you can hook it to which ever battery is closest

[zechariahtheking]

@DrEwBaBy625 so than on one batter will have 2 power wires connected to the power terminal correct.. and will that give the system more power when you add as second battery and than do the big 3 upgrade to get higher voltage

[DrEwBaBy625]

@zechariahtheking yes the one battery will have a line coming in and one going to the amp. this will help increase the amperage your cars power system can put out but it wont change the voltage at all. doing the big 3 will give you 1 or 2 volts. i did it to mine and it got me up to like 14.3v. but the second battery is kinda like a capacitor but better. just make sure you run big enough wires to the second battery

[zechariahtheking]

@DrEwBaBy625 thank you a whole lot... and ya I'm going 2 run 0 guage 2 the battery and for the big 3 upgrade thank you a whole lot I really appreciate it

[ExGhost19]

hey where did you get the fuses at? and the wires?

[DrEwBaBy625]

@ExGhost19 ebay. i bought a 2gauge wiring kit it came with one fuse and fuse block so i had to order another fuse block and fuse

[ExGhost19]

@DrEwBaBy625 thanks man

[MTX8500]

nice vid btw..enjoyed it

[MTX8500]

is it better to hook the amp to the second battery?or does it matter?

[outsidersaudioworx]

helo, can a audio control epicenter help my bass go deeper and louder? tnx

[billiambarnett]

Have you had any issues with the different types of batteries? From what i hear they can work against eachother and eventually crap em both out. Just wondering whats your experiance.

[DrEwBaBy625]

@billiambarnett nope no problems

[outsidersaudioworx]

sir in my place philippines the only alternator i can find is 50 amps only... can i wire my 2 batteries with 50 amps alternator? i need ur help.. can we be friends? i ned ur idea.. tnx

[DrEwBaBy625]

@outsidersaudioworx you could always run 2 50A alts but im not sure that it would be a problem to run 2 batts on a 50A alt. i think my alt is only a 70A

[outsidersaudioworx]

helo, can i wire my capacitor parallel directly to my battery?

[DrEwBaBy625]

@outsidersaudioworx yep! you wire caps and batts the same you just dont need the second fuse with a cap

[mondo82111]

good job

[musician1232]

do u have a HO alt

[DrEwBaBy625]

@musician1232 nope stock

[musician1232]

@DrEwBaBy625 how many amps is the alt

[DrEwBaBy625]

@musician1232 nort exactly sure. i yhink iys only like 70 amps

[TRXfiend]

good vid, how do you do the isolator so you can crank beats when it's not running? cheers dan.

[DrEwBaBy625]

@TRXfiend it would be installed in series with your power wire that goes between the batteries. an isolator is just like a big relay so all it does is disconnect power between them

[booboo83]

thanks alot u tight me well master lol i will inform you when im installin my batteries if anything goes wrong

[floridaboys13]

so your sayin that i need to connect (+,+) and (-,g)... i was thinking to get and extra cable from the alternator to the battery so i can keep it charged. can i do it or i cant?

[DrEwBaBy625]

@floridaboys13 like doing the big 3??

[floridaboys13]

@DrEwBaBy625 well kinda but can i run the wired to the batt right???!!!

[DrEwBaBy625]

@floridaboys13 the second batt?

[floridaboys13]

@DrEwBaBy625 yes

[DrEwBaBy625]

@floridaboys13 it seems kinda pointless since the line connecting your 2 + terminals is already a charge line. but if you want to go all out go ahead it might improve your performance a bit! are you running a stock alt?

[floridaboys13]

@DrEwBaBy625 but the thing is that i dont want my batt to go death??

[DrEwBaBy625]

@floridaboys13 it wont go dead if you have a wire going from the stock battery to your second battery. this wire is also your charge line so as long as it a pretty good size wire than youll be fine. but if you only run like an 8 gauge charge line. it will only be able to draw so much from your alt/ stock batt so it will drain your secondary batt more than your stock one then when your car is off the stock one will charge the secondary one and could kill them.

[floridaboys13]

@DrEwBaBy625 ok so like what size should i get like 4 gauge or what..

[DrEwBaBy625]

@floridaboys13 the bigger the better! id say bigger than 4 gauge!

[floridaboys13]

@DrEwBaBy625 ok . but like do you know like how much thats gonna cost me??? the cable?

[DrEwBaBy625]

@floridaboys13 i got a kit on ebay. it was like $55 and came with ring terminals fuse block and everything

[floridaboys13]

@DrEwBaBy625 ook.. well amma  see what i can do .. if i do it ill post a video..

[DrEwBaBy625]

@floridaboys13 alright just remember its cheaper to do it right the first time

[DrEwBaBy625]

@floridaboys13 i have 2 gauge on mine and the secondary one and could kill them.

[elc0n]

how big is your alternator? And if you drain the 2 battery often whont that kill your alternator after a while?

[DrEwBaBy625]

@elc0n its just a stock alt. im not even sure what it is. i dont usually listen to music with the truck off so i never drain the batts but im sure that over time that could kill your alt. but whats so bad about that? then you get to upgrade!

[deeotto23]

thanx man so much help. I already wired my battery but i didnt have fuses inbetween them and didnt know why i needed one

[wackojerte]

can u still connect the capasitator

[DrEwBaBy625]

@wackojerte yeah if you wanted to but if your doing 2 batteries that should be enugh

[manofthehour12345678]

how many amps are your fuses?

[DrEwBaBy625]

@manofthehour12345678 i think there 150A

[manofthehour12345678]

LOL good video. informational with some humor. thumbs up.

[fastodie]

ALLRIGHT man u got the vid up Thanks i bearly saw it now..well now im sure how to put another battery .and do u still have the original ALTernaterrrr

[DrEwBaBy625]

@fastodie yep stock alt and i dont have the big 3 done. voltage drops from like 13.4 down to 11.8 so i still get alot of drop but its not to bad

[fastodie]

@DrEwBaBy625 WELL i really need another battery or just change the one i got .

my truck battery just died too day for no reason LOL

[ddrking5555]

Great vid man. Really helpful

[battista22]

the drawings for the fuses made the video haha

[darklighter456]

do u have a video on how to hook up a capitator
