Sound Dampening!

This topic just keeps rearing its ugly head. Here is a quote from me on the same topic earlier this year. "Another trick you can do is to get some of that bed liner spray. This not only seals the box but also adds sound deadening and vibration control which helps stop fatege with the MDF, nails or screws, and glue. That's the only problem with using fiberglass resin, It fails over time. At least if the box is used hard. If your design warrants using internal bracing make sure that you router all the edges off so that the air moving inside the box moves smoothly around the brace. I would stick to using MDF strips cut about 2" wide for the braces and make sure that the braces do not touch the woffer at all. Most of all.   Take you time and do it right the first time. Don't let your buddies rush you into building a junker box. Using these methods you will build a box that really rocks(as long as your air volume is correct)."(owner/installer)

brown bread actually sucks. dynamat does not smell.  dynamat is the easiest sound deadener to use.  I would only use extreme though...you get what you pay for here.

Thanks again for all of the input.  I have decided to use Brown Bread.  For $130 on ebay I can get 70 square feet  plus a roller.  I went on their site and looked at the comparison between Brown Bread and Dynamat Extreme and the figures on the BB looked better.  Even if the BB is not as good as the DE I could cover the car 3 times for the same price as Dynamat.  To me I always thought Dynamat was way overpriced, but its all opinion I guess. There is no end to cherry

There is a material called FAT Mat and it works just like Dynamat.  It is exactly like Dynamat buy a lot cheaper. go to www.fatmat.com to check it out.  You can get it on ebay for next to nothing

If i were to order lets say 36 sq ft of fatmat do i just take off my door panels then cut off that plastic sheet and take off one side of the fatmat that will make it sticky and then use a rollers and roll it onto my door? I have a 4 runner will this help me much? Thanksdream it, build it, fiberglass it

i just bought 100sqft of fatmet from fatmet.cim for 119 shiped... check the out!

sorry about the spelling fatmat  and is from fatmat.com cal the up for the 119 price and ask them for it b/c they are having a sale

I have found that the Home Depots in the SOuthern states do not carry Ice Guard, at least here in JAx, Fl, they don't. There is a variations of it called weather Guard. It comes in a RED / white box, is 140sq ft, and costs about $45.95. I have heard it is the same stuff as Ice Guard, and from what I could tell by looking at it, is almost the same texture and weight as Dynamat. 150sq.ft. should be more than enough to deaden the whole car (I think) But there are plenty of alternatives to sound deadening. 1) Fill all big voids (holes) with minimal expanding foam, be carefull it can and will bend the metal if not extremely cautious. 2) Silicone can be used for places that 2 pieces of metal lay over the top of each other, but don't actually connect. 3) Rubberized undercoating stinks, but it good. 4) Rhino Bedliner is great for adding a little mass which will help deaden everything it is on.

Dont have it here in ATL eitherdream it, build it, fiberglass it
