Rockford Fosgate P400-4 400 Watt 4-Channel Amplifier
The P400-4 is perfect for 4-way front-stage/rear-fill or 3-way front-stage/subwoofer systems. Simply drop a pair of component speakers on the front channels and subs on the rear and BOOM--you got "The PUNCH." With its flexible design, the P400-4 is an excellent amplifier choice for virtually any vehicle.Rockford Fosgate Punch Series AmplificationFor over 25 years, Punch amplifiers have set the standard in the car audio amplifier industry and they continue to do so today. It's the reason that they have become the most popular amplifiers in the world. Each of the Punch family amplifiers reproduce sonic perfection along with impressive power in a compact chassis.Perfect for 4-way front-stage/rear-fill or 3-way front-stage/subwoofer systems.Click to enlarge.All connections are recessed into the amplifier's chassis and located on the bottom edge of the P400-4, for a clean, uncluttered install that looks great in any car.Click to enlarge.P400-4 FeaturesFeatures:12dB/octave crossover2/4 channel switch4 Gauge power/ground terminalsAudiophile grade speaker connectionsMOSFET output stageMOSFET power supplyTop Mounted LED IndicatorsCEA-2006 CompliantPower ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.Differential InputsDifferential input circuitry measures the voltage of both the (+) and (-) input signal. The circuitry subtracts the voltage common to both conductors (noise) resulting in only the clean signal. This allows only clean signal to enter the amplifier.DSM (Discrete Surface Mount)DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.Dynamic Thermal ManagementEvenly distributes excess heat across entire amplifier heatsink.MEHSA3MEHSA3reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.NOMADNOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.Punch EQ2Onboard equalizer with up to +18dB @ 35Hz and/or up to +12dB boost at 12kHz.TO-247 MOSFETsRockford Fosgate amps use custom TO-247 MOSFETs. These have 60% more metal tab area for more power capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in competitor amps.TRANS·anaTrans·ana simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality.P400-4 SpecificationsNumber of Channels:4Rated Power:50W x 4 @ 4-Ohms RMS100W x 4 @ 2-Ohms RMS200W x 2 @ 4-Ohms bridged RMSTotal Power:400 WattsDynamic Power:Front Channels86 Watts x 2 @ 4-Ohms 0 degrees Res144 Watts x 2 @ 2-Ohms 0 degrees ResRear Channels85 Watts x 2 @ 4-Ohms 0 degrees Res142 Watts x 2 @ 2-Ohms 0 degrees ResBridgeable:YesEfficiency (average):71% @ 4-Ohm70% @ 2-OhmCrossover Controls:Front High-Pass (HP): 50-500Hz 24dB/octave ButterworthFront Low-Pass (LP): 50-500Hz 24dB/octave ButterworthRear High-Pass (HP): 50-500Hz 24dB/octave ButterworthRear Low-Pass (LP): 50-500Hz 24dB/octave ButterworthTone Controls:Front Punch EQ2 Bass: 0dB to +18dB @ 45Hz and/orFront Punch EQ2 Treble: 0dB to +12dB @ 12kHzRear Punch EQ2 Bass: 0dB to +18dB @ 45Hz and/orRear Punch EQ2 Treble: 0dB to +12dB @ 12kHzFunction depends upon LP/AP/HP switch positionSignal Input:Low level: 2 RCA pairSignal Output:n/aPower Input Connector:BlockPower Wire Gauge:4 AWGSpeaker Output Connector:Screw terminal barrier stripSpeaker Wire Gauge:8 AWG to 18 AWGHeat Sink Type:Cast aluminumCooling:ConvectionRemote Controls:Optional PEQ Remote Punch EQ(overrides built-in Punch EQ2 for rear channels only)Visual Indicators:PowerThermalProtectCircuit Topology Class:Class A/BFrequency Response:20Hz to 20kHz +/- 1dBShipping Weight:8.89 Lbs.
