Zapco ST-501D SQ MINI Sub Amp 1 Channel Class D Mono Subwoofer Amplifier

What makes the MINI amps truly amazing are their extremely small sizes. The ST-64D MINI measures only 15.1 cm (6”) x 8.6 cm (3.4”), and the ST-104D MINI is only 23.6 cm (9.3”) x 9.5 cm (3.7”). These little beasts aren't just small, and they aren't just powerful. They had to earn the Zapco name before we put them into production. But that's still not all there is to these new amps.

They have all the advanced features you would expect... and more. Thanks to a brand new technology, we are able to use the NXP Class D solution to get amazing power and performance in an incredibly compact chassis with over 90% efficiency.

The Mini-Amps Series includes two 4-channel amps with 50 Watts RMS/Ch @ 4Ω (ST-64D MINI), and 95 Watts RMS/Ch @ 4Ω (ST-104D MINI) at less than 0.5% distortion, and a 530 Watts Mono amp. The ST-64D and ST-104D also have the HD Bluetooth Module port, so you can fire up the music on your phone, tablet, or other Bluetooth smart device.
