Sony XM-GS100 GS Series Class D Subwoofer Amplifier
You'll get up to 600 watts RMS of bass power with Sony's XM-GS100 mono amplifier driving your sub. For maximum reliability, this compact amp sports a hefty heatsink that shunts off the heat that's generated when the amp's working hard. The XM-GS100 will also protect your subwoofer, with a Dynamic Distortion Suppressor circuit that rounds off the corners of dangerous square waves, minimizing the destructive effects of an overdriven signal.
All connections are located on one side of the amp, which makes wiring simpler and neater. The tuning controls sit protected under a cover so they won't get inadvertently moved.
