Boost the performance of your motorcycle or car speakers with the Punch - P500X4D. This 500 Watt 4-channel full-range amplifier employs Topology Class D Architecture that significantly improves efficiency without compromise to the sound quality. The Punch - P500X4D has a Frequency Response from 10Hz - 35kHz plus/minus 3dB and it can pump out 500 watts at 1-ohm load without breaking a sweat. The perfect edition to the famous Rockford Fosgate Punch amplifier line-up, the Punch - P500X4D will deliver brute power and its D Class design will offer a higher level of efficiency along with a tri-stage protection that covers thermal, over-current and short circuits. The Punch - P500X4D also features an on-board Punch Bass that can supplement low frequency boom to give your music more impact and presence than a live stadium concert.


With the Punch - P500X4D amplifier, apart from the traditional 4-channel stereo mode, you can bridge both channels to create a high power 2-channel amp, or run stereo speakers on the front with subwoofers on the rear in 3-channel mode. The P500X4D is small but extremely efficient and features like the variable HP/LP crossover and built-in Punch EQ allow precise tuning of Bass frequencies, while the Pass-Thru RCA jacks provide flexibility as your system grows and keeping Y-adapters to a minimum. The included remote lets you control the amplifier's volume level from the front seat.
