I'm looking to upgrade my existing system, starting with the trunk. Right now I'm running two Image Dynamic IDQ 10's with a small 2 channel Alpine in a sealed box. I want to upgrade to something that can make my seats vibrate, or make my nose itch, while still being able to play musically. A single sub setup would be nice because it would save space, but I am not opposed to a dual sub setup, but no smaller than 12's. I dont want to box to take up the whole trunk, so something that is optimal in a sealed box is preferable. If the price is right, I may buy from E-Bay, so if something's retail price is out of range, list it anyways, I'll be checking what everything is going for anyways. Thanks in advance for all the help.
