[gta4isthebomb]

What if you give the amp more than it needs will it hurt the amp?

[r0llinlacs]

@gta4isthebomb no the amp will only take what it needs. its actually better if the power supply can produce more power than the amp demands.

[kent0bmx]

hey would a 860W COMPUTER POWER SUPPLY work with a 444w amp ?

[RWL2011]

@kent0bmx easily in your case, because that sounds like an xplod and they are overrated

[kent0bmx]

@RWL2011 haha yup sure is my mate gave it 2 me coz he got new one or something

[carajoqwe]

i have an apmplifier pioneer 1200 watts, and a PSU 12v 36A thats is correct? or i need 2 PSU? or more A

[jrmartine915]

i have a 800 watt amp with just one sub and a 250 watt power supply will the power supply burn and another ? can i put all my yellows togther for + and all me blacks for -

[jayholley123]

@jrmartine915 no it wont bur n and yes u can

[r0llinlacs]

@jrmartine915 yes it will work. it will not be as loud as it could be though. and yes, its also better to combine the different power rails (yellows) and will give you more power, but is not needed for the grounds.

[RustyNailMediaInc]

Is this too risky for a 1000W RMS amp?

[r0llinlacs]

@RustyNailMediaInc lol might be but i doubt it, the power supplies have all sorts of different "protections"

[Mrantiemo99]

@r0llinlacs but not the cheap ones !!!

[defendant420]

HAHAHA!! I ripped the surround on 3 JL10W6 subs, never thought of duct taping em. (Will Copy)

[RWL2011]

@defendant420 all 3 of them??? that sucks

[elbandolero2012]

yo i got 2 10 inch speackers in a sub but i dont have an amp nd i wanna hook them up to my computer wat can i do to make it work?

[b20002003]

duck tape fixes everything!!!!!

[FungryMan]

Actuall you jump green to black to turn the psu on. pins 14 & 15

[greatsk8erX]

if you can't duck it, fuck it!

[DJPaulFreeman]

Sorry I must be a noob, when you say "create a jumper on the amplifier. Connect the remote wire to the +12v power wire", what is the "jumper" and what is the "remote wire" ?

First time noob (I have 1200 w amp running 2 x 4.5inch splits with 2 6x9's)

P.S. what type of PSU would you recommend?

[r0llinlacs]

The jumper is what it's called when you connect the remote wire to the +12v power.

for 1200 watts you need a pretty nice PSU. Should be at least 1200 watts obviously. But, if you aren't running subs you should be fine with 500 watts.

[93DARIAN]

what psu should i use for 125 watt amp

[r0llinlacs]

a 125 watt PSU, which is pretty much any PSU you can find. The smallest one I've seen was about 280 watts which is plenty for a 125 watt amp.

[IceMasterRob]

hey dude do u repair the sub with tape? XD

thats kind of fun

[ILLTOWN420]

for paper cones the best thing u can use is toilet paper and clear nail polish, works soooooo good

[italianganga]

hey man ive got a problem, i have the same setup prob different speakers, ive got an 800w sub connected through a 150w amp then to a power supply, and it powers up and everything but ive tryed to use one black wire and the red light is still on, then i switch to the other black wire and its still red, i need some help :(

[r0llinlacs]

probably the amp. I assume by "black wire" you are referring to the jumper? It should always go from "Remote turn-on" to +12v power.

[guzbossvid]

@r0llinlacs will a 12V batory charger work to power a amp?

[r0llinlacs]

@guzbossvid yes but it depends how many amps it gives

[GrateMilenko]

Computer power supplys are more powerful then you think they are. They put out 11-16 volts and you can get really nice ones that are capable of 1000 watts. my dad has a two redundent powersupplys that push out 1500 watts a peice for his Blade servers. Goody's Computer Support! hit me up if u need Computer Repairs!

[L00peey]

@GrateMilenko i need repairs on my pc its a lil fucked, obviously im nt givin it to yu but advice wuld be gd

[killthetorment]

@GrateMilenko yeAH TRUST A JUGGALO???

[1alexjessica]

hey u think u can help me and tell me how to set up my subs on to my computer

[1DanielChristensen]

is that speaker held together by tape between the cone and surround?

[elliottjameswalsh]

looks like it

[ThisIs2009]

who cares anyway, it pounds hard!

[r0llinlacs]

Yes. The foam surround was completely toasted.

[lelos14]

@r0llinlacs can u make a tutorial of refroament with tape?;d my car speakers are completly toasted like urs :D

[CTC1922]

Bad quality can't even see what you doing your camera freezes or some shit

[BanControl]

i have a crappy 300w PSU and im trying to make it work for a 1000w amp, will this even work?

[lorenzoruchtie]

Whehe No xD

[andruha11234]

@BanControl 1000 watt rms?

[BanControl]

@andruha11234

yeah

[andruha11234]

then it will most likely not work. Unless you won't push your amo hard... It will work at low level

[BanControl]

@andruha11234

thats what i was thinkin

[666xGuitarplayerx666]

it will power the amp but probably only get it to power on and if its a really expensive power supply, maybe the speakers.

[r0llinlacs]

yes it will work. If you try to turn the amp up too loud, the PSU may temporarily shut off. Also, it will sound horribly distorted at high volumes. But the bottom line is, yes, it will "work".

[bigD0670]

@BanControl you will probably need to use a couple PSU's to make it sound better and to keep it from shutting off. you will need about 84 amps of power to make it sound/work at a normal rate

[r0llinlacs]

@BanControl it will work but you wont get very much sound. and it will be hard on the power supply

[severeflows]

does any body know how to connect a surround sound sub to a computer?

[jonoovbhe]

You mean the home surround sound for like dvd players and stuff? if so then you get the cable thats red and white to a 3.5mm jack. go into an electronics store, they will know what you need. Hope this helped.

[InfamousYG]

hey thats wssupi tape my speakers when it tears ...im suprised to see someone else do it

[FoShizzleMaWizzle]

I just got 2 big speakers, (DJ speakers) I want to connect them to the PC, can some one help me??

what do I need to get them work??

[gaspower70]

easy man, just buy a amplifier and connect the rca's from the computers sound output to the rca's in the amplifiers input

[FoShizzleMaWizzle]

yeah i got it now,, TY man

[SARGENTSCRUFY]

Depending on what your trying to do, you probably should buy a home theater system amp.

[r0llinlacs]

you can use a standard home receiver/amplifier. or you can get a hefty PSU with a car audio amp.

[bboystyle11]

@FoShizzleMaWizzle all u need is a dj amp and some cables a regular receiver and an ipod wire to connect to the receiver and thont put it in to the headphone jack of the computer and it should wor that how i got mine setup

[sawmassacre13]

I have 250w pc supply it gives 30A, Im not sure if it gives full12v daw, I tryed to connect it to a 400w amp but every time i connect the power cables the amp turns on and after 3 sec it turns off, can i get any help ?

[50Centiswhite]

turn down the gain or db on ur amp keep it turn down low till ur able to turn ur reciver up

[r0llinlacs]

well, test different wires. you could be trying to feed it a 5volt or even .3volt wire. so the color might not be the same. try the yellow then try the red and so forth. and make sure its one of the main power rails and not the one that plugs into the motherboard.

[jonoovbhe]

250w is to small for a 400w amp, i have a 450w amp and was using a 450w psu which i fucked up, so used a 400w psu and it blew after about a week of use. try and match the psu to the amp wattage or higher. and make sure you have the yellow wires connected there 12 volts which is what you need. red wires are 6 volts.

[sawmassacre13]

Hey man,............Now I know,.........My 250w psu worked with 400w amp but I couldn't put the volume all the way,.....specially when I wanted to pump the bass,...............So 2 days ago I disconnected the psu and tried to install it back in my pc,......well it fucked up,.......

[r0llinlacs]

sorry dude. should have used a spare one. buy a better one they aren't too expensive.

buuut... you must have done something wrong, because they shouldnt just quit like that.

mine is still going strong and i have NO idea how old it is. it came out of an old pentium 3 system... LOL

[ThisIs2009]

if its the original PSU from it, then its like 9-10 years old :-)

[calvinblinkee]

Why are you using the power supply's wattage rating to match your amps? That rating splits to the 12v, 5v, and 3.3v rails. What you really should be looking for is the amperes rating on the 12v+.

[DJBASS10000watts]

vary true

[WhtMgc]

nice tutorial in the info

why is the sub duct taped???

[r0llinlacs]

lmfao. the foam surround on it went to hell, so i decided not to let the sub go to waste. so i duct taped it! and surprisingly enough, it works perfect

[WhtMgc]

haha nice

but fuck it, whatever works!

[666xGuitarplayerx666]

Yeah, it JL audio dude, that is DEFINITELY worth saving. That hits harder than hell man.
