Rockford Fosgate R2-750X1 Mono Amplifier- 250×1 @ 4-Ohm, 500×1 @ 2-Ohm, 750×1 @ 1-Ohm New

The Prime Series were 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.
