I have a 2015 Genesis with Lexicon factory system, I recently purchased a output converter, kicker sub and amp. I started by trying to get to the 8”sub located in the trunk, but couldn’t get to the wires.. I located the factory amplifier in the trunk and trying to tap into factory system, I have found a couple diagrams for older genesis and genesis coupes, the ones that I have found, do not match up with the wiring harness I have from the factory amp. I just need to know which wires I need to splice into, to send signal to subwoofer. Any help appreciated!!!!!
