If you're looking for a dedicated, bass-driving machine, say hello to the Power T10001bd! Equipped with Class bd technology (Rockford Fosgate's patented subwoofer amp design), this beast produces an amazing 75% efficiency rating with a highly stable output. Even under heavy loads, it will maintain steady power flow and a safe operating temperature, saving your music from clipping and distortion. The Power T10001bd operates safely at 1-ohm impedance, punching out an impressive 1,000 watts! 500 watts RMS x 1 at 4 ohms (750 watts RMS x 1 at 2 ohms) 1000 watts RMS x 1 at 1 ohm (1-ohm stable) frequency response 20-250 Hz Class bd technology CEA-2006 compliant requires 1/0-gauge power and ground leads — wiring and hardware not included with amplifier variable low-pass filter (32-250 Hz, 24 dB/octave) Para-Punch bass EQ (0-18 dB with variable center frequency between 35-70 Hz) with wired remote control MOSFET power supplies and outputs MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability. TOPAZ noise-killing differential inputs eliminate 80% of ground loop noise between the head unit and the amp. TRANS-ana circuitry keeps preamp signal clean NOMAD advanced protection circuitry monitors temperature, voltage, current and impedence, and provides "intelligent" shut-down protection without limiting system performance. fan cooled preamp outputs for easy connection to a second amplifier bd Sync terminal for connection to a second bd amplifier, to drive a common load fuse rating: 150A x 1 dimensions: 17-15/16"W x 2-11/16"H x 12-3/4" MFR # T10001bd
