Plan your installation so that the ampliﬁer is mounted where adequate ventilation is available.

Never mount an ampliﬁer in the engine compartment of a vehicle!

WARNING! Before driving the mounting screws through any surface, be sure of what is behind that sur-

face. Check for gas tank, brake lines, and any vehicle wiring harness.
