I have Pioneers in the front and Kenwood in the back with the stock H/U.

The doors rattle a bit when the bass or volume is up. Anyone know where exactly this rattle comes from and if there's an easy fix?

 

Add a layer of vibrational dampening, such as eDead v1.0, Second Skin Damplifier, or Cascade...

You will need to layer the door panels so they don't vibrate.

 

Yea, for you to even have a noticable difference youll need to dampen the door quite a bit. I mean, youve got to take the door off to begin with and disassemble a lot of your door...might as well do the whole thing. Just dont use Dynamat.

 

Seriously, there is much better stuff out there for MUCH cheaper!

 

Are you sure the rattle isn't more of a crackle...maybe a speaker is blown or falling apart? My doors dont rattle at all and the speakers are getting like 60 rms each. Something in your door might be loose too. Maybe take the panel off and inspect back there.

 

Play a CD that makes the door rattle a lot. While it's playing, press firmly on various parts of the door, inluding handles, switches, and trim pieces. If you can figure out which piece is making the noise, then you can probably fix that in a minute with something laying around the house (foam, tape, etc.).

 

I paid $29 dollars for my Dynamat Extreme a few years back . I put it on my front doors and I am very happy with the results. Having a friend that use to work at an audio shop was great.
