When you first pop the trunk you'll notice 3 Memphis amps and a single Stinger 1700 battery. But if you're lucky enough to witness the full system, you'll gasp when the 3 visible amps rotate 180 degrees to reveal yet another display of amps. I chose Memphis based on their sound quality and power output. Plus, the price was right, and they matched the chrome theme of the car. I am using 4 Memphis ST-1000D's for the subs,(2 bridged for 1 pair of 15s, X 2), and 2 ST200's, one for the mids, and one for the highs.
