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.
