Before beginning, disconnect the negative (-) terminal of the battery prior to working on the
positive (+) terminal to prevent a short to ground. This is important, unless you want to
spend the rest of your life with a nickname like "Sparky," or "Smokey." Reconnect the
negative terminal only after all connections have been made.
To 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 would be in the same location as your amplifiers and or
crossovers. Never mount the component in a location that would subject it to immersion or
exposure to water.
Once a location has been chosen, securely mount the
FRX-456
using the four screws
supplied. 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.
