Audio upgrade help?

[Zori Marfazelian]

So i have a 2015 Chevy Silverado 1500 crew cab with the NON-Bose system. I recently bought a 4-channel amp with new door speakers and a mono amp for two 10 inch subwoofers. To combine the both im going to install the Audio Control LC7i LOC. The issue im having is finding a harness that will plug into the LC7i. The LC7i has 4channels for the speakers and another 2 channels for subs. It also come with a remote section. Is there a plug an play harness that connects the factory stereo to the LC7i? I know LLJ customs makes the wire but their customer service is horrible and i need the system finished relatively quickly. Or does anyone know a T-harness manufacturer that has a harness similar to theirs? Cause i dont want to do any tapping or re wiring, just straight plug and play. Thank you in advance and sorry if this has been asked before

What exactly you are looking for? Do you have any requirements, budget? Let me know maybe I can help you.

Yes there is a way to do it without cutting into anything. Check out my thread on gmfullsize from a few years ago. I can easily return my truck back to stock with this setup. All the harnesses you need along with the steps I took is in the link. Also you can use the red and black from the amp bypass harness for power and ground instead of tapping into the factory harness.
