Rockford Fosgate Power 451S

When you install a Power series amplifier, you get the biggest, beefiest power Rockford Fosgate has to offer. The Power 451S delivers two channels of 115 watts RMS, incorporating the finest circuitry and audio controls available. You'll enjoy uncompromising sound quality, and your music will rock hard!

Steep 24 dB/octave slope crossovers let you tweak the amp's output to best match your system components and musical taste. If you love to "bump", the 451S cranks out 450 watts RMS in bridged mode, and a wired remote lets you control Punch Bass boost (up to 18 dB at 45 Hz) from the driver's seat! Convenient preamp outputs pass full-range signal to a second amplifier in your system.

Specs :

• 115 watts RMS x 2 at 4 ohms
• 225 watts RMS x 2 at 2 ohms
• 450 watts RMS x 1 bridged output at 4 ohms
• stereo or bridged mono output
• 4-ohm stable in bridged mode
• Tri-Way capable
• requires 8-gauge power and ground leads — 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 between the head unit and the amp
• NOMAD advanced protection circuitry monitors temperature, voltage, current and impedance, and provides "intelligent" shut-down protection without limiting system performance
• TRANS•ana 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 boosts bass up to 18 dB at 45 Hz (wired remote control included for fingertip control)
• 11-1/8"W x 2-3/8"H x 9-7/8"D
