Rockford Fosgate Punch

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. 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 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. The P500-1bd mono subwoofer amp dispenses 200 RMS watts at 4 ohms, and it'll deliver up to 500 watts to a 1-ohm load without breaking a sweat. You can tailor the sound with variable-frequency low-pass and subsonic filters, and use the onboard EQ to add some low-frequency ...
