About the Alpine PWE-S8-WRA

Bass for your Wrangler

Whether you're on- or off-road, there's one thing that's missing from your Wrangler Unlimited: deep, accurate bass. Alpine's PWE-S8-WRA compact powered subwoofer installs neatly under your driver's seat so you can add bass without losing any space.

Compact design

The PWE-S8-WRA features an 8" sub powered by a built-in 120-watt amplifier, all housed in a compact enclosure which mounts under your seat with the included brackets. The package also includes plug-and-play wiring harnesses to connect this Alpine sub to the Wrangler's factory or aftermarket radio.

Bass control

You can adjust phase, gain, and the low-pass crossover to tailor the bass to your tastes. You can mount the sub's wired remote on your dash, so you can make easy level adjustments from the driver's seat.

Rugged enclosure

The cast-aluminum enclosure protects the sub and amp from rough on- and off-road conditions. It'll stand up to a thumping and keep on bumping. (Note: this sub only works with Wrangler Unlimited models without a factory sub.)

Features

Installation: The PWE-S8-WRA mounts to the bottom of the driver's seat in select 2011 and later 4-door Jeep Wrangler Unlimited models. The included T-Harness plugs in between the radio and factory harness, and supplies the subwoofer with power and speaker level input. The sub is grounded to a factory ground bolt in the floorboard.

Auto Turn-on: When using the included T-Harness to integrate into the factory speaker level signal, an automatic circuit turns the amplifier on when it senses an input signal.

Low Pass Filter: The amp has a built-in low-pass filter, variable from 50 to 150 Hz.

Wired Remote: Using the included wired remote you can easily adjust the bass output level from the driver's seat (or wherever you mount the remote). The range is 0 to -20 dB, relative to the gain setting on the subwoofer chassis.

Controls:

  • Gain: rotary control; 1.5-30 volts speaker level
  • Low Pass Filter: rotary control; 50-150 Hz
  • Phase: two position switch; 0° or 180°

Connections:

  • Remote: 3.5mm mini-jack for use with the included wired remote

Dimensions:
