R2-750X1

Primed for Performance, the R2-750X1 amplifier is a 750 watt, Class-D, capable of operating at 4 ohm, 2 ohm or 1 ohm 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, and integrated Punch EQ that corrects for acoustic deficiencies while delivering up to 3X the bass. For subwoofers, a variable infrasonic filter and remote level control allows you to tune the bass for the desired level for the music.

Best bang for your buck

The following review is for R2-750X1, which is a part of the bundle you are viewing.

If your looking for a user friendly amp to make life easier adjusting it with causing damage to your subs this is it. It might say 750 watt by 1 ohm but you can actually get closer to 800 watts before clipping if running at .8 ohm you be right at 1000 rms. You won't find and at this price get that close to 1000 rms. Especially being compact. They have been always reliable during the years and test of time for this prime series
