The powerful SI-2100 brings extremely high current power to a custom installed A/V System in a remarkably convenient way. Featuring audio circuitry constructed using the finest materials available, including 1% metal film resistors, high quality capacitors and oversized heat sinks that ensure proper cooling without the need for a noisy fan. This 2-channel amplifier provides 100W per channel (400W when bridged for higher output applications) and independent level control, making installation easier and more straight forward.
