GM/GMC/Cadillac Black & Gray (Without Bose amp) Base Connector 2019-2025

Our 2019-2022 GM/GMC Black & Gary connector 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. Installation Video 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. *For the Non-Bose, Non-Factory Amplified system the connectors will be located behin
