Sound deadening stage II report
I have ordered a bunch of stuff from RAAMaudio and Second Skin Audio a
while ago but so far got to treat one front door only. Since I don't know when I get to the second one I'll post a short summary: I have the doors previously treated with B-quiet ultimate. I pretty much covered all the metal parts with the b-quiet and for some stupid reason (I was experimenting you see) used some synthetic fiber and epoxy on the plastic panel. Well, thankfully the fiber mat came off pretty easily. Expoxy did not make a strong bond to the plastic. So I treated the inside of the plastic door skin with Damplifier and dumped the rest of the Damplifier (I got 10 sq ft to try it out) on the outside door skin over the existing layer of b-quiet ultimate. Then I applied some more of RAAMmat over it. On top of that I've installed about 3 1sq ft pieces of Overkill using V&S 1081 from RAAMaudio.com I also have Ensolite mat from RAAMaudio but haven't gotten around installing it). I think I got quite a bit of improvement after all the trouble. I was testing the install by playing some rattle inducing compositions with bass cranked all the way up and treble all the way down. To my dismay I found that the side mirror for the Protege rattles quite a bit. It's light and it's sealed, I don't think I can pull it apart and apply sound deadener to the casing and the back of the mirror itself. It's a bummer. So I applied tiny little pieces of Damplifier to the crevices on the side that is in contact with a rubber washer that sits between the mirror and the door. Damplifier is very pleasant to work with. It separates where you cut it. But it's expensive. I would recommend to apply Damplifier in the critical parts where you can't apply many layers, such as the plastic door skins and use a ton of RAAMmat everywhere else. So stage II is worthwhile if you like me got something questionable like b-quiet or dynamat before you knew better but stage III probably is not. At this point I probably finally need to get rid of the stock speakers, wife permitting, and cutting the very low frequencies from the door with the crossovers. Which is where I'm having a problem. A decent set of component speakers runs about $250-550 and 6x8s I got a chance to sample sound crappy on the stuff I'm listening to. So the snail paced quest for better speakers still goes on. I should add that Rick has added an automated ordering systems to raamaudio.com (it's very sleek, the shipping rates are very reasonable) and Anthony have finished with the Second Skin warehouse revamp. Just in case any of you are anxious to install more deadener. I also treated the rear deck with RAAMmat and I think I can hear some improvement (more details in the music can be heard I think). But I haven't treated the floor. That is a scary project/ I should probably do the side surfaces in the trunk first though. I don't have a subwoofer yet, just some reasonably good 6x9 woofers. Is it worth it ripping off an reinstalling the trunk liners? |
