Designed to withstand the elements, the M2-500X1 Element Ready™ amplifier is a 500 watt, class-D model, capable of operating at 4Ω or 2Ω mono. This amplifier is extremely efficient because of its class D technology which reduces demand on the 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.

The M2 Series were developed for marine audio environments that feature UV resistant protection and special internal conformal coating that protect the electronics from water. It’s designed for those who want a reliable – with all the power and performance you’ve come to expect from Rockford Fosgate – at an economical price.

The latest generation of M2 Series amplifiers are also designed to be easy to setup and configure, making them perfect for use in any application.

Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.
