Our A/B Class mono block amplifiers combine our new clean low profile design that still has all the necessary features built into an economical package that puts power and control at your command. Features like a MOSFET power supply, RCA pre-amp out, and variable LPF electronic crossover make these ideally suited to add some punch to any system.
The ASA3-400.1 mono subwoofer amp is a great choice when your’re looking to pound out the bass. With 400 watts, there’s plenty of juice on tap to power our S or M Series single 4-ohm woofers.
Wire a pair of 4-ohm woofers in parallel and the ASA3-400.1 will kick out a solid 400 watts. Need more power, then step up to the ASA3-600.1. Both amps are stable to 2-ohms and come complete with a wired remote controller.
