Punch Series Amplifiers are the best value amplifiers in the car audio industry! For 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.

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.

Rated Power power:
50W x 4 @ 4-Ohms RMS
100W x 4 @ 2-Ohms RMS
200W x 2 @ 4-Ohms bridged RMS

Key Technologies of Rockford Fosgate's Punch Series Amplifiers:

Punch EQ2
The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost, up to an 18dB Boost @ 35Hz. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost, up to 12dB Boost @ 12KHz. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.

TRANSana [TRANS conductance Active Nodal Amplifier]
TRANS-ana is a sound quality circuit that is a standard in the recording industry that simplifies the signal path of the amplifier, allowing the signal to travel through the amplifier at a low voltage. The result: Greater reliability, cleaner performance and exceptional musicality, speed, and durability.

TO-247 MOSFETs
Custom designed TO-247 MOSFETs have 60% more metal tab area providing more power handling capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in Most Competitors amps.

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.

DTM [Dynamic Thermal Management]
Rockford Fosgate engineers have developed an award winning cooling design called DTM. This patent pending design seamlessly manages the output of power supply temperatures, while evenly distributing the excess heat across the entire amplifier.

MEHSA3 [Maximum Efficiency Heat Sink Application - 3rd Generation].
MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

NOMAD [Non Multiplying Advanced Decision]
NOMAD is a "real time" analog computer that protects your amplifier from dangerously low speaker impedances and shorting speaker wires.
