Prices vary and everything is built to order. His work is EXCELENT! If you order a kit for audio it includes fans and relay for amp, all hardware marked in separate bags, wired for sub and foam in the sub enclosure to tighten up and clean up the sound. Great sounding setup for a hatch! Pics are of my kit he built for me and installed in my 86. I paid $675. Pricey maybe but well worth it. You can buy his kits on LMR with no audio, but instead storage compartments for around $350 I think.
