## Overview

The Alpine PWE-S8-WRA is a compact, powered 8-inch subwoofer system designed exclusively for 2011-2018 4-door Jeep Wranglers without premium sound. Featuring a built-in 120W Class D amplifier, a custom mounting bracket, and a plug-and-play wiring harness, it delivers deep, accurate bass while preserving cabin space. Its rugged die-cast aluminum enclosure ensures durability on and off the road, with easy-to-use sound controls and a remote bass knob for on-the-go tuning.

## Description

The Alpine PWE-S8-WRA is a bass upgrade system for 2011-up 4-door Jeep Wranglers that do not have the premium sound system with the factory subwoofer. The system consists of the PWE-S8 Restyle Compact Powered 8-inch Subwoofer, a custom bracket to mount the PWE-S8 under the driver’s seat, a subwoofer level knob, and a JK-specific wiring harness for plug-and-play installation. The PWE-S8 is a compact powered 8-inch subwoofer paired with a built-in 120W amplifier, housed together in a cast aluminum enclosure. The PWE-S8 measures just 13.5” L x 9” W x 3” D (at the tallest point) so you can add low, punchy, accurate bass to your JK without taking up usable storage space. The die cast aluminum construction provides durability for ongoing performance, so it’s ready to take the bumps, jolts and other challenges you put your JK through. The amplifier produces 120W continuous power and the quad-coil subwoofer delivers 25Hz-152Hz frequency response. The PWE-S8 connects to the sound system through the auto-sensing speaker level inputs which are conveniently located 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 and use it to easily make bass level adjustments. The PWE-S8-WRA works with an Alpine or aftermarket head unit, or with the factory radio. The PWE-S8-WRA is authorized to be Sold By and Shipped From desertcart. For professional installation, visit the store locator on the Alpine USA website to find an authorized Alpine retailer near you.

Review: Simple install quality product. Expect a couple of hours to install. Very good sound.
Review: Well worth it. I have a 2016 JKU Sahara and directions were accurate. My jeep had the stock system in without the premium sound upgrade. This is definitely the way to go. The bass from this little speaker is great. I do recommend taking the driver side door off when taking the seat out. This didn't cross my mind until I was reinstalling the seat. Install time did take about 2 hrs, but I was also a bit distracted with kids at the time. All in all, install wasn't bad and the upgraded sound is great. Highly recommend!
