Well, I took this morning to line the inside and out with more RAAMmat, and just got done. There is around 18 sq, ft. per door. It's covered really well, and the doors close with that nice heavy thunk. I did the same thing with the gutter screen behind the woofer so I could pack thefactory speaker mount with poly fill. I notice a BIG difference with it. The right side woofer, tended to bottom out on heavy bass passages when turned up loud, (when it bottoms out, you hear a loud POP) Since putting poly fill behind it, I haven't had it pop yet.And I have dropped the x-over point from 65 hz that I was running down to 50 hz. No more vibrations anymore, and now I hear the woofer more than the resonance in the door. Overall, well worth the time........

 

Did you apply anything to the back sides of the inner door trim panels? After I damped the sheet metal in the doors, I noticed that the interior panels started to buzz, since the sheet metal was no longer absorbing the pressure. Now I have to damp those, so that I can get all of that midbass energy to my ears!

 

I haven't yet, but I'm going to tommorrow. I noticed this evening that the passenger window get's stopped about 90% of the way down, ( speaker wire from the amp probably) so I'm going to do it while I'm at it. I stil have about 70% of the second roll left, so I have enough to play with
