So the battery tray is used, but the solenoid was never hooked up. I will include 4ga and all wires need to do this for $75, 1/0 for $100, and I can probably come up with enough to do a big3 kit in either 4 or 1/0. Add $15 for shipping. Fits 03-07 Silverado/Sierra, probably 99-07, but I dont know on that, I have a 04 so.

Blitz Audio active crossover, $25 plus $10 shipping. comes with a bass knob and plexi cover, Im just not going active
Scc1 with Kenwood double din adapter cable, $25 plus $6 shipping

SWI-PC units $25 plus $6 shipping. Barely used and brand new never used wires on that one, might have unused wires for the other too.
