Our 2019-2025 GM GMC Cadillac Aqua & Tan Elite Harness has been tested, redesigned and modified to what it is now by our team at LLJ Customs. The “Elite Series” harness has been years worth of time and effort to provide our customers with a product that will last a lifetime. This option is an all-in-on solution for the ultimate DIY’er. After years of developing our own wire and combining LOC’s, processors, DSP’s and companies like Audio Control and Rockford Fosgate, who offer amplifiers with a high level input signal. By combining these top shelf solutions for the 12V market you can get an entire system upgrade at the same price of a factory head unit upgrade alone.

The Elite T-Harness allows you to add an aftermarket mono amp subwoofers while retaining all the features in your vehicle like the Bluetooth, Steering Wheel Controls and OnStar. This harness was designed for the Non-Bose, Non-Factory Amplified system. You are able to build and customize your harness to your preferences and needs; like the length of the harness or adding an LOC unit of your choice. We offer a variety of choices like an Audio Control LC2i Pro, a Link2 or LinkDQ from Wavtech for when you are just adding a subwoofer s. With an LOC added to the harness you are getting a full plug and play set up; with the harness providing signal and the LOC unit providing RCA out and remote turn on to your amp.

Every unit ordered with the harness will come pre-wired and is tested before leaving our facility. Every product purchased from us comes with a 5 year warranty, including any processors, amps or DSP’s.
