R2-500X4

Primed for Performance, the R2-500X4 is a 500 watt, full-range Class-D amplifier capable of operating at 4 ohm or 2 ohm stereo and 4 ohm bridged/mono. This amplifier is extremely efficient because of its Class-D technology which reduces demand on the vehicles electrical system. The amp also features C.L.E.A.N. circuitry to help you adjust your gain settings, a P.O.W.E.R. supply that generates more power as voltage increases.

The R2 models are developed for car audio fanatics that want a reliable amplifier – with all the power and performance you’ve come to expect from Rockford Fosgate – at an economical price. Rockford Fosgate amplifiers are renowned world-wide for being “under rated,” easily surpassing all specifications, and most importantly, generating more power than their ratings. These 3rd generation of Prime Series amplifiers are refined with the latest Rockford Fosgate technology for easy setup and configuration, making them perfect for use with factory audio or custom aftermarket systems.

Price worthy

All in one for a simple, clean listening experience. Distortion detection built in so you won’t have to guess max volume when setting the gains. Nice sleek design with the performance to match.

Doesn't disappoint!

Fantastic mid-level amplifier. Instantly noticed the power and the clearness of the music. Perfect size for under the seat too. Be careful with the gain to start! Don't move it until you already have music playing... it'll kill your ears! Highly recommend!
