About The Product

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.
