Rockford Fosgate P400X4

Rockford Fosgate's Punch P400X4 amplifier can put out 50 watts RMS to each of your front and rear speakers, plenty of power for clean music even at high levels. You can use the amp's high-pass filter to remove low bass from your speakers so they'll play more efficiently. You can also switch this amp into 2-channel mode to drive a couple of subwoofers with up to 200 watts RMS each. The amp's low-pass filter comes in handy for getting the right sound from your sub/enclosure combo. The Punch EQ2 includes bass and treble boosts, in case you want to add some boom and sizzle back into the mix.

Product Highlights:

• 50 watts RMS x 4 at 4 ohms (100 watts RMS x 4 at 2 ohms)
• 200 watts RMS x 2 bridged at 4 ohms (4-ohm stable in bridged mode)
• CEA-2006 compliant
• Variable high- and low-pass filter filter (50-250 Hz, 12 dB/octave)
• Variable PEQ2 bass/treble boost (0-18 dB at 45 Hz and 0-14 dB at 12.5K Hz)
• Class-AB amplifier design
• Frequency response: 20-20K Hz
• Dynamic Thermal Management and MEHSA MOSFET cooling systems
• MOSFET power and output stages
• Preamp and speaker-level inputs (speaker wire to RCA adapter required for speaker-level input)
• Signal-sensing turn-on with speaker-level inputs eliminate need for remote turn-on lead
• 4-gauge power and ground leads and an 60-amp fuse recommended — wiring and hardware not included with amplifier
• No onboard fuses — when installing multiple amps in a system, an additional 60-amp in-line fuse between the distribution block and the amplifier is recommended
