Chevy Custom/Elevation T-harness trim 4" or 7" Screen R2G

Integrating a subwoofer into your GM factory radio system has never been easier. Our GM T-Harness simplifies the process, eliminating the need for a laptop or complicated steps. Our plug-and-play GM T-harnesses are designed to reliably deliver the signal required to enhance your audio system with quality bass. Our carefully pre-selected active processor options consistently deliver outstanding performance.

If you're looking to fine-tune specific frequencies for optimal results, consider the LinkDQ. Whether you need to boost bass or surpass the vehicle's default signal, the bassRESTOR is the ideal tool for the job. When paired with our T-Harness, which provides both right and left signals along with power and ground to the LOC unit, you can be confident in achieving the best possible audio enhancement for your system.

This harness is tailored to work seamlessly with work trucks, custom vehicles, and those in the elevation trim. To determine if your vehicle falls into one of these categories, look for badges, consult the original invoice or sales paperwork, or check the VIN number. This harness has also been successfully used in various crossovers. For crossover vehicles, it is best to locate the physical connector, often situated behind the screen or behind the glove box.
