I recently put 2 15" speakers in my trunk. The system sounds pretty good but the trunk sounds like absolute shyt. I bought dynomat and dynomatted the shyt out of my trunk and it barely helped. The back deck sounds like shyt AND the rear brake light on my back deck broke because of the bass. I observed where most of the rattling was coming from and it seems like the rattle is coming from where the spare is kept. So i took out the spare and it still sounds like shyt. Anyone have any suggestions on deadening the rattle or anything that'll help? Anyone had the same problem, how'd you fix it? So far the only thing I've heard is that double-sided tape helps the license plate and holds it firm. But how can I neutralize the deck where the spare is and the other stuff. So far foam has also been suggested, however, a local audio shop said that foam builds up precipitation or some **** and causes the metal to rot in due time. I know most of you guys have your own systems, if you can't offer any suggestions, how did you deal with or fix your trunk rattle?

 

Why not buy some of that foam insulation in a can and spray the **** out of everything. It'll firm everything up as well as seal any leaks. Of course it's messy, won't do squat for resale and God forbid you ever want to take it out but it will probbably solve your problem.

 

Which foam spray is this, has it worked for you, and are you sure it'll work, because if it's going to make a big mess and still not help, then that'll just suck

 

Also, has anyone found dynomat successful, exactly where did u dynomat?

 

Anyone try the dynashield spray, is this any good or are there much better foam in a can sprays?

 

People swear by "Peel N Seal"...Cheap alternative to dynomat...Can be found in the roofing section of your local Home Depot or Lowes...

 

Spray stuff sucks.
