Editorial Reviews
From the Manufacturer
Manufacturer's Review (December 30, 2008)
Whether you're looking to drive high frequency component speakers or low frequency subwoofers, the P400-2 has the power and flexibility you need to put some serious PUNCH in your vehicle. Send 100 watts RMS per channel, or 400 watts to a sub in Bridge mode. The power available from such a small amp means it's a great match for a 2-ohm DVC subwoofer or pair of 8-ohm SVC subwoofers.
 The P400-2 features an ultra-small footprint, and clean, simple design that looks great no matter where it's installed. Click to enlarge. |
 All connections are recessed into the amplifier's chassis and located on the bottom edge of the P400-2, for a clean, uncluttered install that looks great in any car. Click to enlarge. |
 The Punch EQ on-board equalization circuit helps correct for common acoustical deficiencies in the vehicle listening environment. Click to enlarge. |
 Rockford Fosgate amps use custom TO-247 MOSFETs with 60% more metal tab area for more power capacity, lower impedance and improved heat dissipation. Click to enlarge. |

CEA-2006 Compliant
Power 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 Inputs
Differential 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 Management
Evenly distributes excess heat across entire amplifier heatsink.
MEHSA3
MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
NOMAD
NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
Punch EQ2
Onboard equalizer with up to +18dB @ 35Hz and/or up to +12dB boost at 12kHz.
TO-247 MOSFETs
Rockford 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·ana
Trans·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.
