Big sound from a small box

Don't have the space for a big subwoofer enclosure, but still want the thrill of sub-bass? At only 3" deep, Alpine's PWE-S8 powered subwoofer fits in all kinds of tight spaces: in the trunk of your car, behind the seat in your pickup, or even under the seat in some cars. And it's made to stand up to life on the road, with its rugged cast metal enclosure that's built to take the hard knocks of a tight installation while protecting your equipment.

In the box

Alpine PWE-S8 side view

At only 3" deep, the PWE-S8 can fit almost anywhere.

Alpines uses a Class D amplifier rated at 120 watts RMS to drive the PWE-S8's 8" shallow-mount, high-excursion subwoofer, so there's plenty of power for your bass. The amp features controls for phase, gain, and a low-pass crossover, so you''ll be able to match the bass up to the rest of your system.

You'll also find an input for a wired remote control that lets you dial in your sound from the driver's seat. Easy-access RCA line-level inputs and speaker-level inputs with automatic turn-on make it easy to integrate this sub into almost any system. The PWE-S8 has everything you need to bring bass to places where there was never the room for boom.

Who needs a powered subwoofer?

To produce bass, you need a sub, an enclosure, and an amplifier, and it can be little tricky to match them all up. A powered sub eliminates all the hassle, as the manufacturer designs the enclosure to house the sub and amp together. This all-in-one solution is especially useful in smaller vehicles, where there's no room to mount a separate amp, or in any vehicle where you need every bit of cargo space. Powered subs range from small, flat boxes that fit under your seat to larger boxes that go in your trunk.

Features

Auto Turn-on: If using the speaker level input, an automatic circuit turns the amplifier on when it senses an input signal. When using the line level inputs you must also use a remote turn on lead.

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

Speaker Level Input: A speaker level input harness is included, making it easier to add the amplifier to a factory radio or to a receiver with no preamp outputs.

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; 0.2-4.0 volts line level; 0.5-10 volts speaker level
  • Low Pass Filter: rotary control; 50-150 Hz
  • Phase: two position switch; 0° or 180°
  • Power Mode: two position switch; SP IN (speaker level input, auto sensing) or REM (wired remote turn-on)

Connections:

  • Harness: the included 12" harness contains power (+12 volts), ground, remote turn-on, and speaker level inputs (left and right)
  • RCA: left and right line level inputs
  • Remote: 3.5mm mini-jack for use with the included wired remote

Dimensions:

  • Width: 13.4"
  • Height: 2.875"
  • Depth: 9.062"

Small subwoofer big sounds

Written By Flys4u, Houston, TX on Sunday, November 30, 2014

Crutchfield Customer Review (What's this?)

I installed this on my Porsche 944. Don't have much room so needed small sub without the big box. This creates so much better sounds than with just speakers.

Pros: Small size. Easy to install. Great sounds

Doesn't make much difference

Written By Julio L., Elk Grove, CA. on Wednesday, October 29, 2014

Crutchfield Customer Review (What's this?)

I didn't expect that this subwoofer would be loud, but I did expect that would improve the sound quality, but it didn't. I have a stock headunit connected to a 4-channel amp that feeds a pair of components and a pair of 2-ways, the adition of the sub didn't make much difference.

Pros: compact size and solid construction

Cons: doesn't kick enough.

Written By Rod L., Wisconsin on Monday, September 29, 2014

Crutchfield Customer Review (What's this?)

I would not buy this product again, nor recommend it, it lacks power output and clairity. There are a number of better quallity subs that pack more output.

Pros: Small in size, easy to mount

Cons: Poor amplification, way over priced! Lacks power

Quality product

Written By Darren, Folsom, CA on Friday, September 19, 2014

Crutchfield Customer Review (What's this?)

Very pleased with this powered sub. I purchased this for my 2010 Ford F-150. It fit perfectly under the rear seat on the passenger side. Build quality of this sub is exceptional. This sub is not cheap, but it also will not disappoint. Install time in my truck was approx 2.5hrs. Sound quality is exceptional if you are looking for fidelity and not to rattle your doors. The sub does include the wired remote. The Crutchfield Overview states the wired remote is an optional assessory... Not the case....Very happy with this purchase

Pros: High quality build, excellent sound/fidelity, fits under the seat of a Ford F-150 ??

Cons: High side of the price range

Crutchfield response on Monday, September 22, 2014 We looked into it and Darren is correct: the wired remote is included in the box with the powered sub. We've updated our records and website accordingly.
