1500-Watt max power, 600-Watt RMS at 4-ohm, 900-Watt RMS at 2-ohm.2-Ohm stable class D Monoblocks.MOSFET PWM power supply We're in a time where small is "in". Smaller, more economical vehicles are more and more desirable. But that doesn't mean you have to sacrifice big power for your system. The new Razor amplifiers pack huge amount of power into small chassis thanks to efficient Full-Range Class D topology and SMT technology. Complimented with every possible preamp adjustment, the Razor amplifiers leave nothing to be desired! Small Compact 4.75" wide chassis allows mounting in very small places where other amps just will not fit. High level inputs allow easy OEM integration. Low pass and High pass x-overs are built in. Durable and rugged MOSFET power supply means these amps are built to put out!
