IMPORTANT: Disconnect the vehicle's negative (–) battery 
terminal before beginning the installation.

Always wear protective eyewear when using tools.

Choose a safe mounting location, away from moisture. Check 
clearances on both sides of a planned mounting surface. Be 
sure that screws or wires will not puncture brake lines, fuel 
lines, or wiring harnesses and that wire routing will not interfere 
with the safe vehicle operation. Use caution when drilling or 
cutting in the mounting area.

Choose a location that provides enough air circulation.

Do not mount the amplifier with the heat sink facing downward, 
as this interferes with cooling.

Mount the amplifier so that it will not be damaged by the feet of 
backseat passengers or shifting cargo in the trunk.
