MATRIX PLUS 6-Channel Line Driver

This unit is insane. My installer at Best Buy recommended it since I upgraded my system so much. I had no idea the difference it would make. I saw reviews saying that it would wake up the car audio system, that is a huge understatement. Even though it's very expensive and the installation also had a fee, I'm very happy with the purchase. I like the ability to adjust the three zones independently. This does more than wake up the system, it brings it to competition level.
