DESCRIPTION

When you install a Power series amplifier, you get the biggest, beefiest power Rockford Fosgate has to offer. The 4-channel Power 851X amplifier incorporates innovative circuitry, precision controls, and MOSFET power to ensure that your music sounds absolutely pristine...and rocks hard!

• 110 watts RMS x 4 at 4 ohms
• 215 watts RMS x 4 at 2 ohms
• 425 watts RMS x 2 in bridged mode at 4 ohms
• 2-, 3-, or 4-channel 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
• MOSFET power supply and output devices
• front and rear 50-250 Hz high-pass/low-pass crossovers, 24 dB/octave slopes
• 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 that eliminate 80% of ground loop noise
• Transana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality
• NOMAD advanced protection circuitry for "intelligent" shutdown protection
• wired remote control included for fingertip control of Punch Bass (for 0-18 dB of bass boost at 45 Hz)
• preamp-level (RCA) inputs
• preamp (RCA) outputs
• 17-1/16"W x 2-3/8"H x 9-7/8"D
