Alpine PSS-23WRA Powered Sound System Upgrade for 2018 - Up Jeep Wrangler Unlimited

Powered System Upgrade for 2018-Up Jeep® Wrangler Unlimited JL

Enjoy premium sound quality even with your JL’s top-off! The PSS-23WRA is a 300-watt 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.

The PWE-S8 subwoofer is engineered to load and disperse lower-frequency sound into the passenger’s footwell area to maximize bass extension throughout the Jeep for great sound with the top on or off. The subwoofer includes 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.

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.

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.

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.
