05-06-2025Purchased this amp along with the Rockford Fosgate Punch Remote Level Control and an InstallGear 4 Gauge Complete Amp Kit. Works flawlessly! I installed it in my 2004 Jeep Wrangler TJ along with two Kicker 2010 Comp Series C10 4 Ohm 10 subs and one Kicker CompRT 2 Ohm 6.75 sub. Works great and made all my Kicker subs hit way harder than they did with my cheap BOSS Audio amp I had until I could afford a better amp. I love how the adjustment dials for this amp are all hidden under the cover so I never have to worry about them getting messed with. The instructions it includes are also very detailed for the initial setup. Rockford Fosgate continues to impress me!

> 3 dayPerfect amp for my pair of Rockford Fosgate P2D4-10s. It came with a bass remote. Also the amp has a distortion detector built in, which is a life saver for setting your amp gains properly.

Power & Bass On Demand!
P500X1BD
The Punch P500X1bd is a mono amplifier capable of producing 500 Watts into a 1-Ohm load.
Due to its dedicated low frequency response, this amplifier is optimized for mid-bass speakers or subwoofers only.
With its super efficient Class-BD circuit topology, the P500X1bd will drop some serious BASS! The stealth top mounted control panel not only provides a sleek finished look to the amp, but it also protects the vital controls.
Our custom heat sink design uses high aluminum mass where it is needed most to maximize heat transfer from the output MOSFETS to the surrounding air, keeping the circuitry cool even under high power and output demand.
