For more provocative output, consider the ACX-600.1 amplifier. LC-5.1300 or D-5.1300 amplifiers provide enthusiastic output, with channel 5 being a superb match. For systems with two Spike Series 2 ohm subwoofers, the LC-1.1500 amplifier is recommended. Consult an expert for configurations with three or more subwoofers.
