JL Audio MHD600/4, M Series 4-Channel Class D Marine Full-Range Amplifier
This compact, multi-channel powerhouse employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 150 W x 4 or 300 W x 2. Tight power supply regulation keeps distortion down and maximizes sound quality.
When using the MHD750/1 to drive a subwoofer system, the MHD600/4 is the ideal satellite amplifier, delivering huge dynamics with pristine resolution. It can also be deployed, on its own, as a very capable 3-channel system amplifier with 150W x 2 to the satellites and 300W x 1 to a subwoofer system.
This marine amplifier features white and gray powder-coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.
Single Cycle Control™
High-Fidelity, full-range Class D is a reality.
R.I.P.S. – Regulated, Intelligent Power Supply
The remarkable R.I.P.S. System ensures consistent power delivery over a wide range of battery voltages and load impedances.
Advanced Rollback Protection
JL Audio's exclusive Advanced Rollback Protection circuit monitors the amplifier's thermal condition and adjusts amplifier operation to eliminate annoying amplifier shut-down events.
RealSink™
Vertical, cast alloy fins effectively dissipate heat, without resorting to noisy fan-cooling.
HD Mounting Options
Two mounting options plus a space-saving stacking feature ease installation.
