Dear MAC AUDIO Customer,
The APM 4.0 car hi-fi power amplifier will enable you to satisfy your high demands on sound reproduction in your car. With its impressive
deep-bass power reserves, low harmonic content and neutral reproduction, the APM 4.0 takes car hi-fi to new heights. The amplifier is
characterized by low operating current, rapid switching capabilities and excellent temperature stability. Increased output power can be
achieved by switching two amplifier channels in an amplifier together in bridging mode. Experience and enjoy how this high-tech machine
perfectly reproduces magnificent sound.
Please read all of the owner‘s manual before installing and using the amplifier.
