Description
MHD-Series Monoblock Class-D Marine Grade Amplifier, 750-Watts @ 1.5-4-Ohms
This ultra-compact monoblock amplifier employs JL's Single-Cycle Control switching design and R.I.P.S. technology to deliver 750W of clean power into any impedance between 1.5 and 4Ω, giving you the highest degree of flexibility in designing your subwoofer system.
Tight power supply regulation keeps distortion ultra-low and maximizes your bass performance. While targeted primarily to subwoofer applications, the MHD750/1 is a full-range amplifier and can also be used to drive high-performance mid and high frequency speaker systems.
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.
