R2 Amplifier Product Overview


Primed for Performance, the R2-750X5 amplifier is a 750 watt, full-range class-D, capable of operating at 4Ω or 2Ω stereo, and 4Ω bridged/mono with a subwoofer channel that can be run at 4Ω or 2Ω. 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, and integrated Punch EQ that corrects for acoustic deficiencies while delivering up to 3X the bass.

In Stock, Good Amp, I'm a Happy Guy!

The following review is for R2-750X5, which is a part of the bundle you are viewing.

Due to the semiconductor shortage, I had trouble finding this unit other places. I was pleased that Sonic had this in stock and shipped it quickly. It arrived in good shape and works well.

The only downside is that RF's documentation is a bit weak. They seem to assume you are already well versed in audio amps and know how to set the various dials/buttons. It isn't rocket science but a few more words might have been useful.
