8" Compact Powered Subwoofer System for '11-'18 4-door Jeep Wrangler JKU


The small, but powerful PWE-S8-WRA consists of an 8-inch powered subwoofer with a built-in 120 watts amp, a bracket designed to bolt the subwoofer under the Wrangler driver’s seat, a remote bass knob and Wrangler-specific wiring harnesses for plug-and-play connection to your aftermarket or factory in-dash system. The powered subwoofer measures just 13.5” L x 9” W x 3” D, so you can add low, punchy, accurate bass to your Jeep without taking up usable storage space.
