Sony Xplod XM-1S Class D Slim Series Subwoofer Amplifier

If you have a small vehicle, the Slim Series XM-1S amplifier's low profile allows it to fit under most front seats. On the outside, the sleek inverted heat sink keeps vital internal components running cooler and lasting longer. Removable terminal covers keep all the wire connections protected and out of sight. The XM-1S Mono amplifier delivers 290 Watts to a single 4-ohm sub, or 500 watts to a pair of subs ? plenty of power for even the most demanding subwoofers. Signal-sensing speaker-level inputs activate the amp automatically when it's connected to a factory radio, so there's no remote turn-on lead for you to install. You can adjust the Low-Pass filter to tailor the signal going to your subs, while a Bass boost adds extra punch to the lows. Switch on the subsonic filter to improve your sub's performance by removing inaudible ultra-low bass. Preamp outputs simplify setup when it's time to add another amp to your system.
