i have finally found out whats rattling in my car due to the bass.......it is the middle seat belt holder thats up on the rear deck...how can i stop it from rattling???

 

Dynomat or expanding foam

 

if i put foam where the seat belt is...it would prevent the seat belt from retracting......any other ideas....??

 

Buy smaller speakers....

You will have to find the parts and 'cushion' them or like stated above dynamat the area around it...

 

Like I say in every noise/rattle problem- Stuff it with Polyfill!

 

what is polyfill?...where can i get it?

 

polyfill is the stuff they use to stuff subwoofer boxes. You buy it at arts/crafts stores and its the fluffy stuff used to stuff stuffed animals and its also good for stuffing doors and everything to get rid of rattles.
