Hello, I’m looking to add a little more bump to my 2015 Tahoe ltz with the factory amplified Bose system. I’ve researched and seen many options, but the one that I like the best is to add a custom harness to the factory Bose amp, which pigtails off and allows you to plug back in the original connection to the amp, another cable to power your aftermarket amp, along with an loc with rca connections to send to your amp. The harness I found is made by llj customs, and I’ll add a picture and link. The harness keeps you from having to splice into any wires, which would void warranty, and also keeps all of your factory system in tact. Has anyone else tried this harness or harness like this, and if so what are your thoughts? I’d rather not have to pull my screen out, so this seemed like the best option for me. Thank you
