Key points
- 1000 Watt mono amplifier with high dynamic power.
- Super-efficient Class-BD circuit topology for strong output with less wasted energy.
- Conformal-coated PC board for enhanced resistance to moisture and corrosive environments.
- Optimized for dedicated low-frequency use (mid-bass speakers or subwoofers only).
- 1-ohm capability: able to drive a pair of 4-ohm DVC subwoofers or a quad configuration of 2-ohm DVC subwoofers.
- Includes technologies: C.L.E.A.N. Technology, MEHSA3, Balanced Differential Inputs, CE Compliant, NOMAD, CTA-2006 Compliant, DSM.
Fit and use
Designed specifically for mid-bass speakers and subwoofers rather than full-range speakers. Use with speaker and wiring configurations that match its 1-ohm capability and mono output to achieve the intended low-frequency performance.
What to know
This amplifier emphasizes low-frequency performance and environmental durability—its conformal-coated board and Class-BD topology suit marine and motorsport use. Confirm speaker compatibility and wiring that support 1-ohm operation to match the amplifier's load capabilities.
Key features
