DIY Crunch Boxx CRBX12 Instructional Video

@ORDuckSeahawk That is not good. You should have assembled the box exactly as instructed in the video. This is a sealed design and will sound bad if it is leaking.

think it be ok to add two 3/4 thick mdf wood on top of a dual ported sub box and gonna put roofing stuff called peel & seal between the mdf boards before i mount it on the sub box

[MrAlexBarclay]

@HoodAudio2 ues "Yellow Glue" wood glue

[HoodAudio2]

why i mean

[HoodAudio2]

well if its not good then my is mike mouning the amp on the box are you saying hes wrong doing with his product

[sicaudiocolorado]

Great job Mike.

[HoodAudio2]

i thought it was bad to mount the amp to the subwoofer box because on alot of car audio forums a guy with the screen name sicaudio says hes a maxxsonics authorise dealers and he be saying that if you mount the amp on the subwoofer box it can cause harm to the amp and maxxsonics warranty dont cover that

[Jacobbz206]

you do know that the amplifier can be mounted anywhere in the car and will receive the same exact vibrations as on the box. the only way to deal with that is by using a sheet of sound dampener on the bottom before mounting it.

[sicaudiocolorado]

not true at all, the sonic vibration that a sub box absorbs is far far more than anywhere else in the car. they specifically designed this setup to sustain the vibration or they would not tell you to do it that way. dynamat will not help much either IMO, just trap heat is all.

[Jacobbz206]

dude.... anywhere you mount the amp all the same vibrations that hit the box will hit the amp. even most peoples amp racks are mounted on their box's and will take the same vibrations since they are touching. and you said dynamat wont help? you dont under stand what it does then, it turns the frequency it absorbs into heat it doesnt trap heat..... you dont know very much.

[sicaudiocolorado]

Obviously you don't know as much as you think you do kiddo. been doing this for a living for over 20 years.

the Medium Density Fiberboard ( MDF ) absorbs 90% of the sonic vibration and reflects it back as sound, that is why they use mdf kiddo. you are thinking of resonation not sonic vibration, 2 totally dif things here.

the spl pressure is not the same everywhere in the car either or they wouldn't use a TL mike at the glass / dash, they would just stick it where ever they wanted too.

[sicaudiocolorado]

" it turns the frequency it absorbs into heat it doesnt trap heat....."

so then it just creates heat lol even better hahahahaha

last thing an amp needs..... a heater mounted to it lolz.

[Jacobbz206]

a good amp doesnt build very much heat if its being used properly. because the amp should only be doing huge surges and getting hot occasionally otherwise its not set-up for daily driving.

[sicaudiocolorado]

putting sound dampener on the bottom of the amp? why does every manufacture say to use wood then? preferably MDF. it doesn't trap heat like dampener either. sound dampener is for something totally different than this .

[sicaudiocolorado]

they make dynamat kits for just about anything, including license plates, so if it was a good idea they would make an " Amp kit " as well don't ya think?

[sicaudiocolorado]

when the manufacturer tells you that you can then of course you can. when we are talking about not mounting the amp on the box, we have almost always been discussing high end spl systems as well, or at the very least a respectable amount of hard hard bass.

a single 300 - 400 watt setup would not fall into that category by any means.

[imbrusx]

that is pretty cool i have to admit it

[artgamez]

Nice video 5 stars

[MaxxsonicsUSAInc]

We appreciate the positive feedback. Keep in mind, this is an entry level package but is intended to help a DIY'er get his/her feet wet.

[crazybroncos89]

very cool mike

[clowno105]

wow thats a pro as kit!!!!!!!

[7501234]

This is so awesome..Why...Because many people are scared to build sub woofer enclosures and this will teach them a little about construction and get them confidence for later down the road to build there custom boxes...Anyways DIY projects make us feel better

[bwc1ngame]

i thought it wasnt good to put amps on the back of boxes?

[TDMaudio]

I thought the same thing, especially because i didnt see any braces in the box.

[BlackHondaCivicHatch]

It had a really good guide on setting your gain there at the end.

[CVRKING20]

yeah a highpower amp LOL thats like a baby amp =)GREAT EASY INSTALL VIDEO!!!

[scottdavenport]

I heard it was bad to mount your amp on the box ?..Any truth 2 this ?

[mmatsjugg]

well if ya got more power than that lol'z

[MaxxsonicsUSAInc]

Very true. In this case you are looking at 300-350wrms depending on voltage drop, a fair small box that is very sturdy, and very little flex. No issues in this application.

[scottdavenport]

Thank you for the quick answer.
