This enclosure is of a closed design to produce tighter, more accurate bass. Also, this enclosure is precision-formed to provide a snug, OE-style fit when installed.

    Trouble-Free Install Procedure. The Kicker PowerStage Amplifier and Powered Subwoofer Upgrade Kit mounts underneath your truck’s rear seat without the need for modifications to your truck. Additionally, all installation hardware and harnesses are included for a trouble-free install.

    Covered by a 1-Year Limited Warranty. The Kicker PowerStage Amplifier and Powered Subwoofer Upgrade Kit are covered by a 1-year limited warranty against manufacturing defects. Please visit the manufacturer’s website for more details.
