Its basically a thick piece of vynal that goes on ur trunklid, or anywhere in your car basically, it reduces the rattling especially when you have subs, you can buy it anywhere, audio shop, bestbuy etc. its pretty expensive tho about $40 for 4 square feet. I did my trunk, rear deck, doors, and rear pillars and man it made a HUGE difference you dont think it would but it really does, i did two layers on everything and my car is practically sound proof.... they also have foam that you can use but I havent use it or know of anyone that has.

its a sound deadener.it comes in sheets you cut it out to fit your trunk or where ever you want to put it and it has one sticky side then stick it to where you want to put it

 

you can also get it sprayed in too i seen a few people use the foam it works but is messy

 

Oh yeah mustanggurl if your worried about your box go to home depot and where they sell the hinges for doors and crap you can find that L shaped plate with screws so you can bolt your box down, it only costs like $4 and its really easy to do...

 

dynamat is the key! You can buy it at any place that sales car audio. Dynamat is noise damping. It is basically the same thing used under the inside of your hood. It would cost alot to do the whole car condisering they would have to remove the carpet, seats etc... You can buy a roll and do the trunk yourself. Thats what I would do. Its really the rear of the car that rattles like hell.

 

I am running 2 12 inch MTX 9500, with MTX 8100 class D amp, Mb Quart 6.5 component set front doors, Mb Quart 6.5 rear, Mtx 275x running highs and mids with 1.0 F Lightning cap. It is crazy loud in the Camaro, considering I have the custom box where the subs fire off the hatch. I have already received two tickets and was told the third strike is a misdemenor!! That sucks

 

Thanks for all the help!! So I just put it under the trunk liner anywhere I can stick it? And that helps the rattling or it makes it so you cant hear the bass on the outside of the car?? Weird.... Never even heard of this stuff!

Also, im probably going to look into getting some of those L-shaped hinges I know exactly what youre talking about... So I can screw the screws into the liner?

 

yes you can put it under your trunk liner and yes it sticks

 

Yeah mustangirl, just screw them down to the liner I wouldnt screw them to the body, and that should be good, I did it to my friends car cuz he had the same problem it was quick and easy and it worked....

Oh yeah an stangkiller you got good taste! how does ur setup sound?

 

Hey guys I finally got the system in and I love it, how ever I have 2 questions, outside the wing on my car rattles like hell, and my lights dim like crazy when I got it really high, one time the subs hit so hard the cd player just turned off, and then i turned the car off later and the battary was dead, am I playing it to much, to loud? do I need a power capacitator? diff. alternator? what about the rattling outside the car?
