DIY: How to Soundproof your Vehicle Under $100
I (a previous Audimute Customer) created a short tutorial in how to soundproof your vehicle using Audimute's 3.2mm Peacemaker sound insulation material. This is high quality, low cost way to soundproof your vehicle. Final Cost about $100 to soundproof your trunk, tailgate, and 4 doors. This is a 1-2 day project, depending on the number of hours you'd like to put in to it.

My review on Second Skin Sound Damping and I compare it to Dynamat. Both great products but I would say Second Skin is better.

Dynamat: Before and After
I Dynamatted my trunk and doors, and what an improvement. Thanks for watching. BTW-I chose this song because it was one of my favorite songs at the time. If you don't like it, too bad. Go make your own video. (and the cheapest place I've found so far is amazon just in case you're wondering ;)
I disabled comments because too many losers without a life kept leaving stupid comments. GTH. :p
Peel and Seal - Volkswagen Sound Dampening
Buy Peel & Seal - http://amzn.to/FPVMx4
Lost the original blog post, so I edited the past Peel & Seal videos together. While Peel & Seal does dampen the noise, I thing proper insulation should also be added. http://youtu.be/M45GXw4egw4

why you should buy sound deadener
Peal and seal roofing is a great low budget alternative to dynamat. ofcourse second skin or dynamat or any other name brand sound deadener is a better product but for 14.98 a roll you cant beat it.
if u try this make sure u get the right stuff. there is a similar product that is just like a thin aluminum tape. thats not it. what u want to use has a layer of tar on it.
