I have replaced everything (MBQ, RF, Alpine) but the HU in my z. it sounds good enough, but the speakers are causing the plastic (i guess) to rattle and buzz. the rear and component especially. any tips on what to use and where to start (problem areas) w/ remedying this problem?

 

gimme something, please. it's driving me nuts and i'm on the fence about getting rid of it.

 

Put your hand on different parts as you play music.

Get some sound deadener or foam and put it on the areas that are rattling.

 

thanks, has anyone used fatmat, dynamat etc. on the plastic panels in the car? for instance the small triangle covering the component?
