Rockford Fosgate Punch 400-Watt Stereo Amplifier Review

Average Reviews:

(More customer reviews)I use this to power a set of Focal 3 way component speakers and together the sound is extraordinary. Highs and lows are super clear even at the highest levels and the highest levels are massive. It is super loud and clear even with the top down at 70mph. I highly recommend this amp.

CEA-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 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 ManagementEvenly distributes excess heat across entire amplifier heatsink.
MEHSA3MEHSA3 reduces 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.
