My Ford Ranger With a Custom box and all electronics made and perfected by Alpine. I have a CDE-HD138BT Deck that controls the two amps in the back. PDX-F4 powering Two SPR 60C speakers in the front with two SPS-517 Coxial Speakers. Than a MRP-450 mono block amp wired into a SWR-1243D for powerful bass inside this small truck. The Custom box helps a lot as well. I Will post picturews of how I wired this and how I covered everthing inculding amps and and wires as well as did the cut outs for the Component speakers.
