KAC-M1814 Compact Class-D amplifier supports louder volume
for Car, Marine and Motorsports users with low-noise.
Plastic covered connector helps to keep out water and dust.
Conformal Coating provides vibration resistance and helps prevent the PCB from rusting.
Pre-amp and Power-amp sections are separated to reduce
radiation noise.
