KAC-M1814Compact 4-Channel Digital Amplifier
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.
Compact design with controlable interface to adjust the sound from a receiver.
