INSTALLATION / MOUNTING

NOTE:

Before beginning, disconnect the negative (-) terminal of the batter y to prevent an electrical short to ground. Reconnect the negative terminal only after all connections have been made.

Mounting

T o prevent damage to the crossover while driving, mount it in a secure place. Choosing the appropriate location will depend upon your vehicle and the complexity of your system design. Typical mounting locations include the trunk and passenger compartment (floor or under seat). Never mount the crossover in a location that would subject it to immersion or exposure to water.

Once a location has been chosen, securely mount the

FRX-456

with four mounting screws. Be Careful! Inspect the area underneath to be sure you are not drilling into wires, brake or fuel lines, etc. that could be damaged by the drill bit or screws.
