The internal amplifying circuitry and the heat dissipation capacity of this amplifi er’s heatsink has been designed to The internal amplifying circuitry and the heat dissipation capacity of this amplifi er’s heatsink has been designed to
cope with 2 ohm impedance loads in stereo mode or 4 ohms in bridge mode. Therefore, you can drive 4 to 2 ohm cope with 2 ohm impedance loads in stereo mode or 4 ohms in bridge mode. Therefore, you can drive 4 to 2 ohm
