PB-120.2 2-Channel Class A/B Amp | Safe and Sound

The PBM-500.1 is the bass specialist of PowerBass’s compact PBM Series, a mono block Class D amplifier built to drive a subwoofer hard from a chassis small enough to tuck under a seat or behind a panel. At Safe and Sound we have spent over 30 years setting up subwoofer systems, and this little mono amplifier is a smart way to add deep, controlled low end without filling your boot.

Big bass in a mini chassis

PowerBass designed the PBM Series to put more power in less space, and the PBM-500.1 brings that thinking to subwoofer duty. It delivers 250W at 4 ohm and 500W at 2 ohm into a single channel, with a high-efficiency Class D design that keeps current draw low while producing a strong, clean signal. That makes it easy to add real low-end punch to almost any system without straining your vehicle’s electrical setup.

Tune your low end with precision

This is where the PBM-500.1 really earns its place. A variable low-pass crossover, a variable subsonic filter and a bass boost EQ of up to 18dB let you tailor the output to your subwoofer and your taste, while the included wired remote gain control puts bass level adjustment right at your fingertips from the driver’s seat.

• Mono block, 2 ohm stable, high-efficiency Class D
• Variable low-pass crossover (50 Hz to 250 Hz)
• Variable subsonic filter (10 Hz to 50 Hz)
• Bass boost EQ, 0 to 18 dB at 45 Hz
• Wired remote gain control included

Built to survive where other amps fail

The internal circuit board is conformal coated with a transparent protective layer that guards against moisture, dust and extreme temperatures, making this mini amplifier a natural fit for motorcycles, UTVs, off-road vehicles and marine-style builds. A self-diagnostic protection circuit guards against impedance overload, speaker short circuit, thermal overheating and DC output, shutting the amp down before any damage is done.
