Rockford Fosgate Punch Series - P500-1bd

500 Watt Class-bd Mono Amplifier
With its super efficient Class-BD circuit topology, the P500-1bd will drop some serious BASS! Due to its dedicated low frequency response, this amplifier is optimized for mid-bass speakers or subwoofers only. No need to worry because its 1-ohm capability will drive a pair of 4-ohm DVC subwoofers or quad-configuration of 2-ohm DVC subwoofers with ease

12dB/octave crossover

4 Gauge power/ground terminals

Audiophile grade speaker connections

Infrasonic filter

MOSFET output stage

MOSFET power supply

RCA pass-thru

Top Mounted LED Indicators

DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

(left-OLD | right-NEW)
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.
