GM/GMC/Cadillac Aqua & Tan (Without Bose amp) Base Connector 2019-2025

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 preference
