Great advice. Doing mad research now!

I forget what they're called, but you might want to look into a 'back wave absorber to place directly behind the speakers (assuming you're using stock location). The idea is to absorb the backwave so it can't bounce back and interfere with the woofer. You can pay $50 bucks for a name brand or just use a paper egg carton. But make sure you waterproof it first so it doesn't mold.

Honestly installing sound deadening isn't really any more of a pain than your own stereo install anyways. I ended up having to dremel out stock speaker grills and stuff and create custom mounts. Then when I had all the panels and trim off before I laid any cable I put down deadener. Just make sure you do it all at the same time so you dont have to rip apart your car twice.
