I just ran a Rockford Fosgate power supply whatever from the battery to the trunk. The wires ran right up to my (must me 5-6 years old now?) Alpine deck. Whole set up cost me $400. Subs, amp, deck and wiring. Sound quality is unreal! I can make it do the soulja boy or the honkey-tonk stomp. Just depends on how you set it up and balance your audio in your car.
