I recently traded my F150 and removed my stereo. You're welcome to take all the items pertaining to the stereo set but I'm listing the amp, subs and box as the primary items. I removed the LOC and some wires with it as well that you can have.

These were strong enough to rattle your teeth or flex the windshield, if you're into that kind of thing. I listen to country music though and it rounded off the system with a very crisp rumble and punch.

Rockford Fosgate P1000x5D - 1000w x 5ch
Two ARC10v3-2ohm subs (high quality)
Dual FoxBox enclosure for SuperCrew

Asking $500 (roughly $400 lower than I paid for it all). Located in DFW.
