      High-Quality Audio Performance. Adding this Kicker SubStage Powered Subwoofer Upgrade Kit to your Sierra 1500's audio system is the best way to enhance the quality of the sound system without the hassle of replacing the factory speakers. This subwoofer system creates a rich and powerful sound with the help of a 200-watt amplifier and a Digital Signal Processor (DSP). Furthermore, the DSP is specifically tuned to the truck’s system and is designed to produce the clearest bass sound out of the speakers.

      High-Strength and Stylish. Kicker crafted this SubStage Subwoofer System using a high-powered circular subwoofer with a built-in plastic enclosure that has exceptional thermal management. It is also engineered using computer-aided technology for a precise, custom fit. Moreover, this high-strength construction is flexible, highly scratch-resistant, and is specifically built to handle your truck’s dynamic lifestyle.

      Simple Installation. This Subwoofer Upgrade System is designed for easy installation with no cutting required. It simply mounts directly into factory location and plugs without modification to your truck’s interior. The bolt-on installation competes with basic hand tools and light-to-moderate mechanical skills required.

      Limited Warranty. Kicker warranties the original purchaser of the SubStage Powered Subwoofer Upgrade System a 3-year limited warranty from factory defects in material and workmanship under normal use. This warranty is valid only if the product is purchased from an authorized Kicker dealer and used for the purpose for which it was designed.

      Application. The Kicker SubStage Powered Subwoofer Upgrade Kit is designed specifically to fit all 2007-2013 GMC Sierra 1500 Extended Cab models.
