Rockford Fosgate Punch amps
Rockford Fosgate continues to develop progressive sound technologies. Their aim — to produce a smaller amplifier, with all the power and clarity you expect from the Punch name.
Dynamic Thermal Management
The award-winning "Dynamic Thermal Management" 3-stage cooling system uses forced air to dissipate heat evenly across the amp and out through the heatsink. The internal components in these compact amps stay cooler, resulting in higher efficiency and lower distortion. You get more installation options, without sacrificing wattage or audio quality.
MEHSA cooling process
MEHSA is a Rockford Fosgate proprietary process that increases the heat transfer from the MOSFET devices to the heatsink. This allows the heat to escape more readily from the amplifier, so that the transistors stay cooler.
P400-4 Punch performance
The P400-4 4-channel amp dispenses 50 RMS watts per channel to your front and rear speakers, or you can bridge it for 200 watts RMS into two channels for your subs. You can tailor the sound with variable-frequency high- and low-pass filters, and use the onboard EQ to add some high- and low-frequency punch to compensate for your car's acoustics. An optional wired remote control lets you tweak the sound from the front seat for quick adjustments while you're on the road.

Accessories
Please Note: You may have disabled JavaScript and/or CSS. Although these accessories are still accessible, certain functionality is unavailable.
Amplifier Wiring Kits
Rockford Fosgate will extend the warranty on your amp by one year when you buy their kit with the amp. Note: Wiring not included with the amp.
Stereo Patch Cables
The suggested wiring kit includes only one stereo patch cord, and you may need two for a 4-channel amp.
Speaker Wire
Bring the music from your amp to your speakers.
Remotes
Add a remote and control your amp from the driver's seat.
Capacitors
Protect your charging system and improve your bass with a capacitor. Ground cable and connectors required (not included).
Firewall Bushings
If you drill a hole in your vehicle's firewall for your power cable, guard against corrosion, get a watertight seal, and protect your wiring from chafing against the cut-out.
Dual Amp Wiring Kits
If you are hooking up more than one amp, here's how to get it done. Note: Make sure you have enough patch cables.
Fuses
You'll need an 80-amp fuse to safely operate your amp.
Test Discs
Tune your system like a pro with Test CDs.
