DESCRIPTION

When you install a Power series amplifier, you get the beefiest power Rockford Fosgate has to offer. The Power 851S will feed a big, power-hungry subwoofer all it can handle this beast delivers an awe-inspiring 850 watts RMS in bridged mode. Innovative circuitry and precision controls ensure that your music sounds absolutely pristine... and rocks hard!

• 215 watts RMS x 2 at 4 ohms
• 425 watts RMS x 2 at 2 ohms
• 850 watts RMS x 1 at 4 ohms in bridged mode
• stereo or bridged mono output
• 4-ohm stable in bridged mode
• Tri-Way capable
• requires 4-gauge power and ground leads and a 60-amp fuse wiring and hardware not included with amplifier
• variable 50-250 Hz high-pass/low-pass crossover, 24 dB/ octave
• TOPAZ noise-killing differential inputs eliminate 80% of ground loop noise
• NOMAD advanced protection circuitry monitors temperature, voltage, current and impedance, and provides "intelligent" shut-down protection without limiting system performance
• TRANSana circuit designs keep voltages low and signal paths simple in the pre-amp section, for minimum distortion and maximum musicality
• MEHSA provides more efficient transfer of heat from MOSFET output devices to the heatsink for cooler operation
• preamp outputs for convenient daisy-chaining of amplifiers
• Punch Bass (0-18 dB at 45 Hz) with wired remote control
• 17-1/8"W x 2-3/8"H x 9-7/8"D
