R2-750X5

Primed for Performance, the R2-750X5 is a 750 watt rated, full-range class-D amplifier capable of operating at 4 ohm or 2 ohm stereo with a mono subwoofer channel that can be run at 4 ohm or 2 ohm. The front/rear stereo channels can also be run at a 4Ω bridged/mono load. 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 dynamic power as voltage increases, and an 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.
