Pure Performance
Monoblock amplifier for subwoofer use and particularly ideal for the SR Series.
1200 watts x 1 (1 ohm), 800 watts x 1 (2 ohm) and 400 watts x 1 (4 ohm) continuous power. CEA-2006 Compliant specifications for true, accurate power ratings.
2400 watts x 1 (1 ohm) dynamic power.
1 ohm stable design can drive even the most demanding subwoofers.
Super Efficient Class D Pulse Width Modulation amplifier design. Draws less power and runs cooler so you won't heat up the inside of your vehicle or make the headlights dim.
High-speed MOSFET switching power supply and high current Bipolar Output Transistors pump maximum voltage and high current to your speakers or subwoofers.
Double Layer Fiberglass Epoxy Printed Circuit Boards for more rigidity, less shrinkage and a smaller overall amp footprint.
6-Way Smart System Protection (SSP) circuits
Beautiful Functionality
