WHOLE cabin except for doors and rear package shelf have 1/4" foil-faced rubber. I might still do the package shelf and doors some day. The original roofing felt divider between trunk and rear seat was replaced with Masonite covered with the same insulation on the cabin side but nothing on the trunk side. Been wondering if that rigid panel is acting like a drum and transmitting trunk noise to the cabin. Thought about insulating the trunk side of the divider but don't like the thought of looking at foil in the trunk. Need a good idea for covering the trunk side of the divider with some sound-absorbing material. Thought of ceiling tile like material. Or maybe the foil-faced rubber under trunk liner material. I have some of that -- maybe enough. Don't think I'll use roofing felt.
Dynaliner, works good, that's what I used on the divider in my trunk. It's less expensive than Dynamat, and works in conjunction with other sound insulators. http://www.dynamat.com/products_car_audio_dynaliner.html
That looks good. Did you leave the roofing felt in place to avoid having the sticky side exposed in the trunk? May have to find a piece of felt and discard the Masonite.
I put it so, it faces the trunk. You can see the Dynaliner logo from the trunk. It's between the divider board, and the supports. I'll see if I have a picture.
I have found that foil back will hold paint. I have some left I am going to put in my trunk behind the rear seat when I finish installing my new seat covers, "whenever I get them". I have a piece of 1/2in MDF board behind the seat back that I had a large 10" sub mounted. I did'nt like the performance of that setup so I remove the the spkr and left the MDF. I don't have anything on the MDF now, it's resting against the seat braces. Im going to put some P&S there and paint it. I don't have any thing on the quarters. I was afraid if I have to make a repair there of having to get the stuff off. I do have it on the metal behind the doors in the rear below the quarter glass. I don't have much of an issue w/ noise frm exhaust. I have a generic brand mufflers that are relatively quiet " I love em". When I got the car it had Cherry Bomb straight thru's. They got on my last nerve. I got rid of them vry shortly after I got the car. I don't know if the Dynaliner is all that more efficient than what u already have; especially since u already have it. I wud be more inclined to put it on a overhead surface, hood or roof where weight maybe an issue. JMO
Huh, works on my car, it's nice and quiet, but then again, I didn't use something made to seal roofs as a sound deadener....
Great! In most cases present day sound/noise deadners are multi-purpose materials. Granted, some do one thing better than others, depending on the primary design parameters. Most multi-purpose/universal things work better in one direction than the other. In some cases, it's not so much what's used - it's the end result....
Mojo (or Everett)....if you would have faced the sub into the trunk...I think you would have like the performance better.
Evening Craig------ Mojo or Everett - I respond to both. Do prefer birth name. No big deal.... I was getting resonance/vibe's from the metal surfaces in the trunk. Ur probably right; If I had faced all the trunk area I probably wud have eliminated some of it. I do believe there's a reason the spk mfg's. and sound/audio installers/specialist use MDF "low resonance". I have built enclosures in the past from 3/4MDF according to the spkr mfg's drawings/plans and was very satisfied w/ the results. However, the trade-off was utilizing more vechicle space. I bought a small sealed ready made box for the sub I had behind the seat and it's much better audio now. I prefer building my own - but I wanted it like right now. I plan on building one for the Comet or taking the one out of my Windstar "8" sub" ported enclosure and putting the 10" in the van - where space is not an issue. Im bascially the only who rides in the car so I can afford to use the space for the sound/audio setup. "My main goal is not more volume frm the sub" just bring out parts of the audio spectrum it was designed for. I leave the window rattling to the younger crowd.
