Compact marine subwoofer for tight spaces

The Pyle PLMRSBA8 is an 8-inch slim active subwoofer built for under-seat or low-profile installations in boats and vehicles. Its marine-grade waterproof construction withstands moisture and splashes while the integrated amplifier removes the need for a separate amp. A remote level control lets you adjust bass from the driver position.

Upgrade from passive or non-marine subs

This unit replaces a passive subwoofer that would require an external amplifier and extra wiring, saving space and install time. The jump is worth it when you need waterproof durability plus a self-contained 100W RMS amplifier in a 12.8" x 9.5" x 3" enclosure that fits where larger boxes cannot.

Limits of the built-in amp and crossover

The onboard amplifier delivers 100W RMS with a peak rating of 600W, so output is constrained by that power ceiling rather than by a separate amp choice. The adjustable low-pass filter operates between 50 and 150Hz, and input sensitivity ranges from 0.12V to 3.5V, defining the signal levels and frequency band the system can accept.

Questions about this item

How much clearance do I need under the seat for the 12.8" x 9.5" x 3" enclosure?

The enclosure measures 12.8 inches long, 9.5 inches wide and 3 inches high, so you need at least that much flat space plus room for the wiring harness and the mounting brackets that ship with it.

Which wires must be connected for high-level speaker input and where does the remote level knob plug in?

Use the supplied hi-level input wire to tap the factory speaker leads, set the adjustable input sensitivity between 0.12 V and 3.5 V, then plug the remote subwoofer control cable into the dedicated jack on the amplifier panel.

What should I check if the red protection LED lights up after the install?

The red LED signals overload, thermal or short-circuit protection; verify the power and ground connections, ensure the impedance load is correct, and let the built-in amplifier cool before restarting the system.
