The PSS-21WRA is a direct fit sound system for 2015-2017 4-door Jeep Wranglers without the factory upgraded sound system. This 320-watt, 9-speaker sound system is optimized for the Wrangler and installs into the cabin without using taking up much storage space, yet still delivers quality sound. The system consists of the PWE-S8 powered subwoofer, SPT-70 6.5-inch 2-way component speakers with 1-inch silk dome tweeters (to replace the factory speakers in the sound bar), SPT-71 6.5-inch 2-way component speakers with 1-inch premium silk dome tweeters (to replace the factory speakers in the dashboard), an MRV-F300 V-Power 4-channel amplifier, remote bass knob and wiring harnesses. Brackets to mount the subwoofer and amplifier under the passenger seat plus other installation accessories are included. The PWE-S8 is a compact powered 8-inch subwoofer with a built-in 120W amplifier, housed in a cast aluminum enclosure. The PWE-S8 connects to the sound system through the auto-sensing speaker level inputs on the side panel. The side panel also gives you access to Phase, Gain, LP Crossover and Remote Sub Level controls for proper sound setup. Mount the separate subwoofer level knob on your dash to easily make bass level adjustments. The PWE-S8 measures just 13.5" L x 9" W x 3" D and mounts with the MRV-F300 amplifier under the front passenger's seat using the supplied brackets. Besides using minimal space, this design lets the lower frequency sound load and disperse into the passenger's foot well. This delivers maximized bass performance throughout the Wrangler, even when the top is off. The PSS-21WRA works with an Alpine or aftermarket head unit, or with the factory radio. The PSS-21WRA is authorized to be Sold By and Shipped From Amazon. For professional installation, visit the store locator on the Alpine USA website to find an authorized Alpine retailer near you.
