INSTALLATION/MOUNTING

NOTE: As an option, before beginning, disconnect the
negative (-) terminal of the battery to prevent an
electrical short to ground. Reconnect the negative
terminal only after all connections have been made.

To prevent damage to the 

MaxxBass

®

Processor while driving,

mount 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 

MaxxBass

®

Processor in a location that would subject it to immersion or
exposure to water.

Once a location has been chosen, securely mount the 

MaxxBass

®

Processor with the 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 bits or screws.
