i have a pretty good system that, when i turn it up, rattles the hell out of my car. I have an eclipse headunit, Pioneer 4-way speakers, rockford wiring, Rockford Capacitor, Cyclone 800 watt amp, 2 Polk Audio 12" subs. It kicks pretty hard so I know i'm going to dynamat my trunk at least.

My question is, even if i dynamat my trunk, will my doors still rattle the same? or will the trunk absorb some of that and lighten the rattling of the whole car?

thanks

 

Your doors MIGHT rattle alittle bit less but I doubt you will be satisfied. Your bass response will be much better because the resonation of your trunk will decrease greatly and it won't be as loud as on the outside of your car but you will still get rattles on the inside.
