The M.45 discrete Class D mono amplifier is deceptively powerful for its tiny stature. The chassis only measures 6.89″ x 6.89″ x 2.07″, but this sprite puts out a walloping 500 watts at 1Ohm.

Its control panel features all the adjustability needed to make the necessary tweaks for fine tuning the amp to your system.

What we didn’t include are unnecessary space cramping features that are more marketing than performance based. The control panel includes your gain, subsonic and low pass filters, RCA input, daisy chain output, and remote gain control port. This is the perfect amp for those space constrained installs that still need enough punch to drive a real subwoofer.
