        Comments about Jl Audio M400/4 Full-Range, Class D 2/3/4 Channel Marine Amplifier:

        This amplifier is currently driving 2 pairs of JL 7.7 CCS speakers on the bridge of a 380 Carver Santego. The system gets many compliments on how clear it is at higher volume levels. I won't consider any other amp except possibly the MHD series from JL but I prefer the power supply technology in the M series.
