Pyle 8-Inch Low-Profile Amplified Subwoofer System — 600W Marine Underseat Subwoofer with Built-In Amp (PLMRSBA8)

Product overview

The Pyle PLMRSBA8 packs an 8-inch slim woofer and a built‑in amplifier into a compact enclosure designed to fit under seats or in tight spaces. It delivers a noticeable bass boost to everyday listening, enhancing playlists, movies, and on‑the‑go audio without taking up valuable space in boats or vehicles.

With a total output potential of 600 watts peak, this system blends power and efficiency in a single, enclosed unit. The amp contributes 90 watts RMS while the woofer handles 100 watts, delivering coherent bass that complements midrange and treble frequencies rather than overpowering them. The result is enhanced drive‑by bass that can be felt in the cabin or cabin‑style interiors while keeping a low profile.

Flexible inputs and easy integration

The PLMRSBA8 supports both low‑level RCA input and high‑level speaker input, making it compatible with a broad range of head units—factory or aftermarket. This flexibility can simplify wiring and help preserve signal integrity in diverse installations.

An assortment of indicators and controls keeps setup intuitive: a blue LED for power status and a red LED for protection status provide quick at‑a‑glance feedback. A remote bass boost control lets you tailor the low end from the cockpit or seating area, while a delay remote turn‑on helps minimize pops when powering on.

Fine‑tuned bass and practical controls

Dial in bass depth with a 0 or 180° phase shift option, and adjust for your space with a 0 to +12 dB bass boost at 50 Hz. The low‑pass filter ranges from 50 to 150 Hz, helping keep sub‑bass focused where it belongs. A configured input sensitivity range of 0.12 to 3.5 volts supports a variety of source levels and listening preferences.

The enclosure measures a compact 12.8 by 9.5 by 3 inches, and comes with mounting hardware for straightforward underseat installation. This setup aims to deliver audible bass without crowding cockpit or cabin layouts, making it a practical upgrade for tight spaces.
