Core Highlights & Features

• High-Excursion 7″ × 7″ Square Driver: Square cone geometry yields greater effective surface area than standard circular subwoofers of the same footprint, moving more air for tighter, deeper bass.

• Upgrade your car audio with the Alpine PWE-7700E-EL ultra-compact underseat powered subwoofer. Features 150W RMS, 7×7″ square driver, and slim 74mm cast body.

• Built-In Class Power: Delivers 150W RMS (300W Peak) of clean, distortion-free output tailored specifically to the enclosure volume.

• Ultra-Slim Profile (74mm Depth): Measures just 7.4 cm thick, easily sliding under passenger seats, behind truck benches, or inside compact trunks.

• Alpine PWE-7700E-EL Underseat Powered Subwoofer (150W RMS, 7×7″ Square Driver)

• Rigid Anti-Resonance Housing: Heavy-duty cast enclosure minimizes acoustic resonance and unwanted chassis vibration, keeping low frequencies accurate and punchy.

• Broad Low-Frequency Response: Extends down to 10 Hz up to 150 Hz for articulate basslines, kick drums, and synthetic sub-bass.

• Seamless OEM Integration: Accepts both high-level (speaker wire) and low-level (RCA) inputs, enabling clean integration with both factory factory radios and custom head units.

• Factory car speakers simply can’t reproduce true sub-bass. The Alpine PWE-7700E-EL Underseat Powered Subwoofer delivers the rich, articulate low frequencies your sound system is missing—without consuming a square inch of usable cargo space.

  At the core of the PWE-7700E-EL is an innovative 7″ × 7″ square woofer. By using a square cone, Alpine captures 20% more radiating surface area compared to a conventional round driver of the same outer dimensions. Paired with a built-in 150W RMS amplifier housed in a rigid, anti-resonance cast metal enclosure, you get deep, clean bass down to 10 Hz without rattles, chassis resonance, or distortion.

  Plug-and-Play Integration: Whether your vehicle runs a modern touchscreen factory radio or a custom aftermarket receiver, installation is simple. With high-level speaker inputs, low-level RCA jacks, and auto turn-on sensing, the system hooks right up to your existing audio harness without cutting factory lines.

Introducing the sleek and powerful PWE-7700E-EL, an extraordinary addition to your car audio setup. This compact marvel allows you to enhance your system with great sounding bass, without compromising your car’s precious space. Measuring at just 255mm wide, 190mm tall, and a mere 74mm deep, the PWE-7700E-EL delivers an impressive 150W RMS of bass output through its high-excursion 7×7″ square subwoofer.
