Metra Amp Bypass Harness for 2003-2004 GM Trucks, SUVs & Hummer H2 with Bose (70-2050)

An amp bypass harness for 2003-2004 GM trucks and SUVs with the Bose amplified system: Cadillac Escalade and Escalade EXT, Chevrolet Avalanche, Silverado, Suburban and Tahoe, GMC Sierra and Yukon (including Denali and XL) and Hummer H2. It lets an aftermarket radio drive the speakers with the factory amp bypassed.

The vehicle must carry both RPO codes UQ7 and Y91 for this harness to work; the code list is usually on the glove box sticker. The factory amp sits under the center console, and since it contained the crossovers, add crossovers for the subwoofers and tweeters. Confirm fitment for your vehicle's trim and factory audio system before ordering, or book the install with our Chilliwack bay.
