Lizzord30 Posted August 12, 2011 Report Share Posted August 12, 2011 I am replacing the door panels with different ones from my conquest and notices their is no insulation or plastic behind the door panels on my Starion anyone have tips on doing this? I would like as good or better then stock sound dampening, but at cheap/free lol Also Plan to try to fit my 150Watt 6 1/2in 2 way speakers in the stock location. Any tips for that? Hope I can keep the stock look. Thanks for any help! Link to comment Share on other sites More sharing options...
Lance_S Posted August 12, 2011 Report Share Posted August 12, 2011 (edited) Lizzord, I have a system in my car. I have dampened the doors with mat and I went through the process of dampening the whole car. I used 5 lb carpet backing (which is cheap) and 3m spray adhesive. The whole trunk and floor and firewall of the car has that. I then got a roll of rubber roofing, it's around 30 to 40 mills thick and glued that to the carpet backing. This put a floating layer (carpet backing) between the car and the rubber roof mat which is your sound deadener. It significantley quited the car down. For the door I used a second skin type product. Peel and stick. Double up behind the driver. I run a 6 1/2 inch massive audio driver in the door. I use a tupperware bowl that perfectly fits the driver for a homemade box. It also seals the driver form the back side so moisture doesnt ruin it. The tweets i put in the vynal covered panel just above and and infront of the mid range. Just use a hole saw for that. Fill the tupperware bowl with baffle material before you insert the driver. The back of the needs to be reinforced with 1/4 luan because there is a space between the interior panel and the door panel. Fill the void in the door panel with playdo or clay type material that doesn't harden. Then screw the 1/4 luan to the inner door panel over the puddy. The interior door panel will now pull up tight and eliminate any rattles. Slide the bowl in first through your new hole, then your driver, then use long screws to go through the driver, interior panel, 1/4 " luan, and finally through the sheet metal door panel. Don't worry, there is plenty of room behind the driver to fit the magnet. The RK6 massive audio magnets are extremely large, some of the largest in the industry. Yours will fit. I will try and post some pics later, this computer doesn't have them up. Edited August 12, 2011 by Lance_S Link to comment Share on other sites More sharing options...

Burton Posted August 14, 2011 Report Share Posted August 14, 2011 Are you wanting to sound deaden or just replace the wind plastic? The sheets that stick too the door frame behind the door trim panel are only there to keep wind and drafts from getting from the door itself into the interior of the car. Without the sheet you'll notice drafts around the door panel, door handles, and window switches. That plastic doesn't do anything for sound deadening. You can use a little adhesive around the edge and lay a nice thick plastic paint drop cloth type material in place of it. For sound deadening you can use any of the lay in or spray in sound deadeners, but many of those get pretty expensive. Even some rubberized undercoating sprayed in the right places can quiet stuff down and it's pretty cheap. Link to comment Share on other sites More sharing options...

I do have some Undercoating spray where are these "right places" that i can use this? Link to comment Share on other sites More sharing options...

Now we say heck with the wieght I will just build a more powerfull motor!!! Haa Yea Ill start at low PSI so I can add goodies and just raise it as the stuff goes in On a side note I found some plastic stuff in the shop looks like would work well to seal that up Now to find some insulation laying around Link to comment Share on other sites More sharing options...
Burton Posted August 15, 2011 Report Share Posted August 15, 2011 Well, pretty much spray it in anywhere that you have a rattle or squeak. The "right places" are wherever the car needs deadening Link to comment Share on other sites More sharing options...

Burton Posted August 15, 2011 Report Share Posted August 15, 2011 I mean do you know problem places on the car? Well, most of the squeeks and rattles in the doors are from wore out window tracks and such, but you don't really want to be going and coating the window tracks with undercoating. However, using a heavy grease in the tracks will sometimes quiet the rattles down to an extent. When I've done sound deadening in SQs, I've pretty much covered everything I could. I use the roll on sheets on all the larger metal areas that are easy to get at, then spray the undercoatiing in the nooks and crannies where I couldn't get the other stuff into. I pretty much lay the roll on mat stuff on the trunk floor, the backs of the 1/4 panels, the back of the door skin, all the inner structural supoport areas of the interior, and then fill in with undercoating in the hard to get places. If you're looking to just target certain areas, you'll have to drive around and listen for rattles and try to pinpoint the areas that the noise is coming from then concentrate your deadening in that area.

emann420 Posted August 20, 2011 Report Share Posted August 20, 2011 (edited) The plastic is used as a vapor barrier between the moisture accumulated along the window, that eventually drips into the door and is either evaporated away or is released through the drain holes at the bottom of the door skins, and the inner side of the door panel. "I think". As far as the sound damping goes, one layer on the outer side of the inner door skin, one layer on the inner side of the outer door skin and two more patch panels of damping on the inside of the outer door skin right behind the speaker worked for me. I managed to get all the rattles out of mine except for one light bulb inside the passenger side tail light. Up to 135dB http://s1088.photobucket.com/albums/i336/themremann/1989%20Conquest%20Done%20by%20Me/?action=view¤t=DoorDynamated2.jpg E Edited August 20, 2011 by emann420 Link to comment Share on other sites More sharing options...

Indiana Posted October 6, 2011 Report Share Posted October 6, 2011 Ya, a door panel that's been on the car for awhile and that plastic is gone will warp. Its just cardboard and when it rains water drips down off the glass and blows around and runs out the bottom of the door. They were putting plastic behind the cardboard door panels at least in the 50s maybe the 40s too but I've only worked on one car from the 40s and it didn't even have an interior, that is until I made it all.
