My 1999 Mustang GT rattles really bad in the trunk with my 2 10's facing the rear of the car in my trunk. Is there anyway possible to locate the speakers more inside of the actual car and less in the trunk, but still achieve a good amount of sound from the speakers? The rattle is mixing in too much with my subs, and I'm not willing to spend hundreds of dollars on dynamat or whatever, just to cover it up. If anyone knows of a place to locate the subs other than the trunk, let me know.

 

try looking at other brands beside dynamat like brown bread. It was about half the price of dynamat and has lasted me through 3 pheonix summers. Unless you are going to get pretty custom there are really NO options to put subs in the passenger compartment and even then you are just going to transfer the rattles to a new place........

 

Put them under the hood, always increases SPL, SQ, hell EVERYTHING!

Sound Deadening is not expensive, well no where near hundreds atleast. I myself use and recommend Hushmat. It sticks like crazy, and does it's job. You can get a "door kit" that comes with 10-12"x12" sheets for like $65 I think, and thats enough to cover a decent amount of your trunk area. Also if your license plate is the source of most of the rattling, remove it and simply look at a way to rig something in there so it doesn't rattle against your car. My DD car I put a few rubber washers at each of the 4 corners and that took care of it, depending on your stang you may only have top mounts so..... rig something!

I dont know how all these guys are getting so much rattling on their stangs, my trunk is gutted to the metal and you can almost not hear my stereo more than 15 feet from my car, let alone any rattling from the outside, and not much from the inside.

 

I can't honestly tell you why there's so much rattle now. My speakers in the back rack crapped out on me a few months ago, so I decided to just remove the whole speaker rack and leave myself more room for a sub box. I still have the default amps installed, but no mids in the back. Maybe the sound is coming through the holes, who knows.
