About this product
4 Ch. Class D Full-Range Marine Amplifier, 400 W
Installation tips
- Size power and ground wire to the amp's current draw and fuse it within 18 inches of the battery.
- Keep the ground short (under 18 inches) to bare metal on the chassis.
- Set gains with test tones or an oscilloscope — the gain knob is not a volume knob.
- Mount it where it can breathe; amplifiers need airflow to stay cool.
