I used to have a huge stereo in my old Oldsmobile back in high school. Then I transferred it to my 1G DSM when I had that. Since then haven't bothered much with it because my car is a huge bitch too, so when I get a truck or nice dd, then I'll consider some stereo again.

I have to agree, expanding foam is not a very good thing to use for sound deadening and can wreak havoc on any panel you spray it behind. Stick to the tried and true methods joel.It is not a very good product to use on anything for that matter.

expanding foam does not work at all for sound dending unless its a full room and ur sealing the cornersactually, it kinda does work by applying pressure to a panel to keep it from rattling. But just spreading it on does nothing.

...and you should be careful what it is you are applying it to. it has been known to break windows, door frames, and even heave foundations.

well sound only matters from the inside right forget the foam and jsut enjoy the musics....and a few bumps never hurts nothing

In fact, by applying dynamat or any other sound deadener (Roadkill, brownbread, Cascade, etc....) you can effectively quiet the interior to the point where it would be the rough equivalent of doubling your amplifier power. Its not uncommon to gain 3 decibels of sound pressure by stopping rattles...and 3 decibels is the same as doubling your amplifier power. Just to clarify, that does not mean it is twice as loud. You need to get 10 times the amplifier output (on the same number of speakers) to get twice as loud (10 decibels). In other words if you make 90dB at one watt w/ 2 watts of power you will only make 93 dB; w/ 10 watts you will make 100dB, w/ 100 watts you will make 110 dB; and w/ 1000 watts you will make 120 dB (and this is only in a perfect environment, usually you make less of a difference by going up in power by 10 times the normal amount...say 7-8dB for every time you increase power 10 times)
