Premium Sound Upgrade

Enjoy premium sound quality even with your top off! The PSS-23WRA2 is a 300-watt sound system upgrade featuring a powered subwoofer, amplifier, and tweeters for the 2018-23 Jeep Wrangler Unlimited JL and Jeep Gladiator JT.

Bass that will Turn Heads

The PWE-S8 subwoofer is engineered to load and disperse lower-frequency sound into the passenger’s foot well area to maximize bass extension throughout the Jeep for improved bass you can feel. Included with the subwoofer is a remote bass knob so you can control the bass level from the convenience of your dashboard. The Included 4-channel amplifier more than doubles the power over the factory system allowing you to enjoy your tunes with the top off.

Simple, Bolt-in Installation

The PWE-S8 Powered Subwoofer and KTP-445U Power Pack Amplifier mount directly under the passenger’s seat with the included mounting brackets and come pre-connected for easy, bolt-in installation.

Crisp, Clean Audio

The included SPR-10TW-WRA High-Performance Component Tweeters replace the factory tweeters on the top of the dash and add a high-frequency response for crisp, clean audio that is lacking in factory Jeep systems.
