MOUNTING Mounting To prevent damage to the FRX-322 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 for your new FRX-322 would be in the dash or center console. 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-322 using the two supplied brackets.

WIRING Factory Ground wire may need to be replaced if it is frayed or broken. Positive Battery Terminal Fuse must be installed within 18" of battery Run signal cables (RCAs) and remote turn-on lead down the opposite side of the vehicle of the power wire to avoid radiated noise. Drill a hole in the firewall and use a rubber grommet to keep wire from shorting.
WIRING The next step is to connect the Power, Ground, and Remote wires to your FRX-322. The power wire should run from the mounting location through the vehicle to the battery or power distribution block. Avoid sharp corners, creases, and sharp body parts. When passing through any metal wall (i.e. firewall etc.), a grommet must be used to prevent the wire from chaffing and shorting to ground. The ground wire should be of the same gauge as the power wire.
FUNCTIONS 1. Power After connecting the Power, Ground and Remote wires, plug in the PowerLock connector here. 2. Low Pass Output Plug the RCA cables from the FRX to the Low Pass amplifier inputs. 3. Front Input Plug the RCA cables from the front channel output of the headunit to the FRX Front Input RCAs. 4. Rear Input Plug the RCA cables from the rear channel output of the headunit to the FRX Rear Input RCAs. 5.

TROUBLE SHOOTING NO SOUND Is the LED lit? YES Check Input cables for signal by connecting them straight to the Subwoofer amplifier NO Check Power and Remote turn-on wire for voltage. Make sure Ground wire is secure. ANY SOUND NOW? YES NO Problem is in the Crossover. See your Problem is elsewhere in the system. local Authorized PrecisionPower Dealer Check head unit and amplifiers. or call1-800-62POWER. SOUND IN ONE CHANNEL ONLY Reverse left and right RCA outputs for one band (i.e. subwoofers).
