Product details

Powerful Bass in a Compact Package

The Alpine PWE-S8 8" Amplified Subwoofer delivers punchy, accurate bass from a slim, space-conscious design. Its built-in Class D amplifier and 8" high-excursion woofer are housed in a durable die-cast aluminum enclosure, making it a practical upgrade for a cleaner, more dynamic vehicle sound.

Smart, Space-Saving Design

Measuring 13.5" L x 9" W x 3" D at the tallest point, the PWE-S8 is engineered for tight spaces. Its shallow-mount profile lets you tuck it under a seat, behind a seat, or into a trunk, hatch, or other compact area without sacrificing cabin or cargo space.

  • Peak power: 240 watts; RMS: 120 watts
  • 8" woofer with high-excursion cone
  • Frequency response: 32–150 Hz
  • Cast aluminum enclosure for durability and rigidity
  • Built-in Class D amplifier for efficient power delivery

Flexible Connections and Tuning

Wiring is straightforward with RCA or auto-sensing speaker-level inputs located on the side panel. You’ll also find accessible controls for phase, gain, a low-pass crossover, and a remote sub level to tailor bass to your listening space and music style.

  • Side-panel inputs and controls simplify setup
  • Phase, gain, LP crossover, and remote sub level options
  • Authorized to ship from Amazon for convenience and reliability

Real-Life Scenarios

In a sedan, SUV, or pickup, the PWE-S8 adds low-end authority to daily drives, weekend road trips, and commute playlists—without demanding a large install footprint. The design prioritizes steady, controlled bass that complements a wide range of genres.

Whether you’re upgrading a factory system or building a more immersive soundstage, Alpine’s engineering focuses on consistent performance, ease of installation, and enduring materials. For professional installation, you can locate an authorized Alpine retailer near you via the official store locator. The result is a discreet, capable sub that can elevate the overall sound signature of your vehicle while keeping setup flexible and approachable.
