Take Your Wrangler’s Sound Beyond Factory

Enjoy premium sound quality even with your JL’s top off! The PSS-23WRA is a 300 watt powered system upgrade featuring a powered subwoofer, amplifier, and tweeters for the 2018-Up Jeep Wrangler Unlimited JL without the factory amplified system. The PSS-23WRA provides excellent sound performance whether the JL’s top is on or off.

Sound That Will Turn Heads With The Top On Or Off

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 great sound with the top on or off. 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.

Easy Bolt-in Installation

The PWE-S8 Powered Subwoofer and KTP-445U Power Pack Amplifier don’t take up much since they mount under the passenger’s seat. The two products come pre-connected for easy, bolt-in installation with simple wire routing. Mounting brackets for the products are included as well.

Simple Tweeter Replacement

The SPR-10TW Component Tweeters replace the factory tweeters on the top of the dash. These high performance tweeters add much needed high frequency response that is lacking in the factory Jeep JL systems. An EQ Ring improves the tweeter’s dispersion characteristics and delivers a wide, flat frequency response.

Works With Any Radio

The included T-harness gets the necessary audio signal connections from behind the Wrangler’s radio, making installation a breeze. The PSS-23WRA is compatible with Alpine universal head units, the factory Jeep base radio, or other aftermarket radios.
