Just DON'T get eDead. I love my eD amps, but would never go with their deadener after seeing the tests done on them.
I can tell you this though, Audio Technix is one of the best deals you can get. I Ordered 25sqft of the 60mil, and with only half of it down on my trunk lid and rear-deck lid, it was a DRASTIC improvement. You'll be amazed by it and won't regret it one bit, I promise. Just save up a little more for something you know you won't regret.
