R2-500X1

Primed for Performance, the R2-500X1 is a 500 watt, class-D amplifier capable of operating at 4 ohm or 2 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. Perfect for subwoofers, a variable infrasonic filter and remote level control allows you to tune the bass for the desired level for the music.

Can't go wrong with Fosgate

It's small but back in the days you needed an amp that was 4 feet long (lol) to come close to this little monster.

Great little amp

Paired this with an R2-300x4 and a Kicker L7 10. Love the clean clip light for input and output. Makes installing and tuning the amps extremely easy

Big Power small package

The new tech built into this small package is going to be hard to beat at this price point. Fast shipping is great also.
