Awesome setup Those must put out some serious bass and sound pressure! I don't even want to imagine what it would be like to sit in the back seat...come to think of it, I don't think I even want to be in a car next to you I only have a single 10" in the back and almost had to pop a few asprins when I first had it...and I don't even have my amp cranked more than 40%. I guessed I'm just getting old
