Adding a Sub to your new 2019 and up GM factory radio has never been so easy. Our GM T-Harness design truly works as advertised and doesn't need a laptop or overcomplicated steps. Our plug and play GM T-Harnesses are guaranteed to deliver the signal you need for adding quality bass. The Gm T-Harness and active processor options we pre-selected for you will over deliver, every time.
Want to target and modify a specific frequency for better results? Take a look at the LinkDQ. Maybe you have no bass or want to go past what the vehicle (or a flat signal) can deliver? the bassRESTOR will be the best tool for the job . The patented technology means, no turn-on pop when using the audio turn on feature. As well as no dead radio screen, given that we just use the audio and don't mess with the Canbus system. Other features like clip detection let you know when the signal you're using from your vehicle is starting to bottom out and introduce distortion.
For non-Bose, non-factory amplified systems, you'll find the connectors behind the glove box, near the kick panel. Make sure your vehicle has the black and gray connector, as they can't be swapped or used in place of the Aqua and Tan connectors. Ordering the wrong color may lead to installation delays. In the case of Colorado/Canyon vehicles, the connector is located behind the screen
* Harness is 24 inches in length and will come pre terminated and wired to the unit selected.*
Please verify the connector colors in the vehicle BEFORE ORDERING, this is a final sale item. Thank you

Not all wire is created equal so ...
Why Shock-Wire©?
Shock-Wire© was created to combat the idea that you HAD to pull new wire in your vehicle when you replaced of amplified your factory system. The only solution at the time was speed wire aka 9 wire.
