DESCRIPTION

When you install a Power series amplifier, you get the biggest, beefiest power Rockford Fosgate has to offer. The 4-channel Power 551X incorporates innovative circuitry, precise audio controls, and MOSFET power to ensure that your music sounds absolutely pristine...and rocks hard! The 4-channel design allows you to use the 551X in a variety of applications, from powering full-range speakers to driving subs.

• 70 watts RMS x 4 at 4 ohms
• 140 watts RMS x 4 at 2 ohms
• 275 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 — 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
• Trans•ana 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-level (RCA) outputs
• 12-1/8"W x 2-3/8"H x 9-7/8"D
