The C3d 2-channel full range Class AB amplifier is designed to provide the highest fidelity from the most minimal footprint.

It features a compact 6.9” x 13.1” x 2.03″ chassis and is rated at 250 watts x 2 at 2 Ohm. It has plenty of power to drive multiple components in a stereo configuration.  You can also bridge this amp to 4 Ohm mono and get a clean 500 watts x 1 for use with a subwoofer.

For durability, we used a heavy trace double sided PCB, set-screw speaker/power terminals, and panel mount RCAs.

The C3d also features fully adjustable HP/LP/BP crossover networks, and the ability to work with an optional remote gain control.
