Love the builds and ideas here! I went down the rabbit hole and started to gut my 22 LTZ Z71. The BOSE amp is the devil, and there is really only one solution out there to get a clean signal and that's the Axxess AXDSPX-ETH1. It is a DSP giving 31 bands of EQ and will give a flat signal after removing the BOSE amplifier. I went with a complete active setup, ordering the Audio Control ACX600.6 for the doors and ACX600.1 for the sub. I wanted to keep a small footprint and these amps are tiny! I am replacing all the speakers with Audio Control PNW-69 in the doors, PNW-275 in the dash and PNW-65 in the rears along with a single 10" SPK-10S2 Sub under the rear passenger seat. I was able to find a custom enclosure color matched to the interior from a shop in Florida. Super excited to get this project under way!!
