I am looking at a rockford fosgate power 120001bd amp.
750 watts RMS x 1 at 4 ohms (CEA-2006 Compliant) » 1,500 watts RMS x 1 at 2 ohms » 2,000 watts RMS x 1 at 1 ohm » 1-ohm stable » frequency response 20-300 Hz » Class bd technology » 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 » variable phase control (0°-180°) » 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 » fuse rating: 250 amps » dimensions: 23"W x 2-11/16"H x 12-3/4"D » warranty: 2 years
should i get a 2 ohm sub or a 4 ohm sub? 2 ohms would give me more power. so is that a good idea?
