Rockford Fosgate Punch P1000-1bd-1,000 RMS x 1 at 1 ohm Mono subwoofer amplifier

 Rockford Fosgate Punch P1000-1bd Rockford Fosgate continues to develop progressive sound technologies, aimed at producing a smaller amplifier with all the power and clarity you expect from a Punch amp. The award-winning "Dynamic Thermal Management" 3-stage cooling system uses forced air to dissipate heat evenly across the amp and out through the heatsink for cooler internal components. This Class-BD amplifier combines the best features of traditional Class AB amplifiers with the efficiency of the Class D design for lower distortion and less power draw. Its smaller chassis gives you more installation options, without sacrificing wattage or audio quality. The P1000-1bd mono subwoofer amp dispenses 250 RMS watts at 4 ohms, or you can wire your subs for a 2- or 1-ohm load to achieve higher power output — up to 1,000 watts. You can tailor the sound with variable-frequency low-pass and subsonic filters, and use the onboard EQ to add some low-frequency punch to compensate for your car's acoustics. Product highlights: mono subwoofer amplifier 250 watts RMS x 1 at 4 ohms (500 watts RMS x 1 at 2 ohms) 1,000 watts RMS x 1 at 1 ohm CEA-2006 compliant Dynamic Thermal Management cooling system variable low-pass filter filter (35-250 Hz, 12 dB/octave) selectable subsonic filter (28Hz, 12 dB/octave) variable bass boost (0-18 dB at 45 Hz) optional wired remote Class-BD amplifier design MOSFET power and output stages (uses TO-247 MOSFETs) preamp-level inputs preamp outputs 4-gauge power and ground leads and an 140-amp fuse recommended — wiring and hardware not included with amplifier no onboard fuses — when installing multiple amps in a system, an additional 140-amp in-line fuse between the distribution block and the amplifier is recommended 14-1/4"W x 2-1/4"H x 8-1/2"D warranty: 1 year
