Here's a speaker setup for an F-150, years 04-08, fits the supercrew models, may fit on the supercab but im not quite sure. Box fits perfectly underneath rear seat, giving it a factory look. Its a professionally built sealed box with two Kicker 12's. I even had the box covered in carpet to match the rest of the interior. The amp is a Memphis Power Reference and the complete wiring kit is Kicker along with the protective fuse-box. Nothing but quality, as speaker guru's would know. Setup has only been used a couple of months. Everything works perfectly and ive never had a problem with any of it, im only selling it b/c I sold my other f150 and bought a newer one and it came with the factory woofer and doesn't sound too shabby so im keeping it in. I paid over 750 for the entire setup and im asking only 450. If it doesnt sell here its going on ebay as an auction. Let me know! Pm or call, 337-519-3282
