I know some of you have sound deadened your L's. What product did you buy, where can I buy it, what did you cover and how much of it did you use? Any suggestions in putting the material in would be helpful along the way. Thank you

 

There is a product called DYNOMAT. Thats what I use for my truck. You can get it at any place that sells audio stuff besides circuit city. I installed it by glueing the mat to the mettal. So of my friends have use velcrow but it doesn't seemed to do so well. The parts that I covered was mainly the door jams and the surrounding edges also the floor boards. Now I can play anything and nobody can hear anything. I use about 3 sq. ft. and it was about 4 bucks a foot.

see ya

Dynamat is expensive, there are products that are the same out there, for much cheaper. I need more info from other people though, I think TampaSVT did his? you there tampa?

 

well if you want inexpensive go with installation foam than. you can get it at your home depot. Its about ten bucks and you can do everything. The only problem is that it smells and it is really messy.have fun

lol, no no no, im not doing that, eww, i was thinking the brand B- Quiet, they have out ranked dynamat in AS&S magazine in a test with other sound dampening products

 

I've used both. Dynomat is a better product, IMHO. Conforms better with heat and doesn't tear as easy.

B-Quiet is just cheaper, but if you hit it up with a good stereo shops, you can get the Dynomat in bulk. Don't try buying it by the package. Will cost a fortune...

Word of caution:
I sound proofed everything. Floors, back wall, doors, interior pieces, etc. If you cover the holes in the back wall, consider turning off the pass. side airbag. Soundproofing makes the cab nice and quiet, but also makes it air-tight. You could loose an ear drum if the bags go off.

 

Talk about timing! LOL

Yesterday I just applied some dampning to the back wall of the L. I found some stuff from McMaster-Carr called Hi-Temp Mastic and figures for the price I'd give it a try. It's VERY similar to Dynomat and ALOT cheaper. It cost $12.79 for a 32"x54" (~13sqft) and is pretty easy to work with. It made a noticable difference! I figure six sheet should cover the ENTIRE cab (both doors, backwall, floorpan and roof) for less than $80. Only bad thing is, you can't put multilpe layers of it, it won't stick to itself. No biggy really since it seems to work very well with just one layer.

BTW, the part number is 9709T18, hi-temp mastic.

 

i was looking at the mcmaster stuff too, is there any way i could make it stick to itself cause i want to double layer the floor and rear panel

 

Lay a piece of masking tape on the edges that you want to cover... It'll stick to that.

 

I just got done doing mine too and I posted a topic on it earlier. I did what Rich did and covered the vents and he is absolutely correct on the part about being air tight. I can feel the pressure on my ear drums when I shut the doors and when the A/C goes on. Luckily I've ruptured the linings in my ears so they can't hold that much pressure

Best stuff for the best price. Its pretty much a generic dynamat extreme. Use this with a layer of asphault mat (dynamat original or hi-temp mastic) and a layer of foam and you probably wont hear that cop right behind you trying to pull you over for just looking fast. It is also light.

*note* im not related in any way to that seller. he is the only person I know of that sells the product (hence it being called raammat)
