Rockford Fosgate PM500X1BD Punch Marine 500W Class-BD Mono Amplifier

The Rockford Fosgate PM500X1BD is a 500-watt mono amplifier featuring high dynamic power using Class-BD technology and a conformal coated PC board designed for motorsport and marine applications. Class-BD amplifiers deliver 75-80% efficiency ratings compared to traditional Class-A/B amplifiers' 20-60% efficiency.

Power Output:

• 150 watts RMS x 1 at 4 ohms
• 300 watts RMS x 1 at 2 ohms
• 500 watts RMS x 1 at 1 ohm

Key Features:

• Optimized for mid-bass speakers or subwoofers with dedicated low frequency response
• 1-ohm capability drives a pair of 4-ohm DVC subwoofers or quad-configuration of 2-ohm DVC subwoofers with ease
• High-level input capable with auto turn-on circuit
• On-board Punch EQ with +18dB boost @ 45Hz
• 12dB/octave Butterworth crossover with low-pass filter (50-250Hz)
• NOMAD protection system guards against shorting speaker wires and dangerously low speaker impedances
• C.L.E.A.N. set-up with input/output clip LEDs to help match source to amp and optimize output
• Optional remote Punch Level Control (PLC2) ready with input clip indicator

Marine-Grade Construction:

• All components protected against harsh outdoor elements including dust, UV, temperature, water, corrosion, and vibration
• Marine-grade two-part epoxy coating on circuit boards
• Marine-grade stainless steel hardware
• Cast aluminum heatsink with stealth top-mounted control panel

Power ratings conform to CTA-2006 industry standards, ensuring real power numbers rather than inflated marketing ratings. The robust, conformal-coated construction ensures reliable performance and durability in demanding motorsport and marine environments.
