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.

Problem is in the RCA cable.
1. Attenuation- Push this switch in to accept high level RCA inputs (up to 8v) or direct speaker lead inputs from common grounded (not high powered) headunits.See diagram below for wiring.
2. Combined Inputs- Push this switch IN to connect Front and Rear Inputs. Leave the switch OUT for front/rear fading.
3. Rear Inputs- For fading rear fill, connect the rear RCAs from your head unit here.
4.Front Inputs- Connect the front RCAs from your head unit here.
5. After connection- After connecting Ground, Remote, and Power wires, plug in the
Powerlock
connector here.
The next step is to connect the Power, Ground, and Remote wires to your
FRX-456
. 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 chafing and shorting to ground.
The ground wire should be of the same gauge as the power wire. As a rule of thumb, use as short a length of wire as possible. Find a location near the
FRX-456
that is metal (the floor is ideal) and clean an area about the size of a quarter to bare metal. Dr ill a pilot hole in the middle of this area. Be Careful! Inspect the area underneath to be sure you are not drilling into wires, brake or fuel lines, etc. Terminate the wire with a ring connector and attach it to the bare metal using a #8 sheet metal screw and washer (not supplied). We suggest crimping and/or soldering this connection. After the connection is complete, coat the area with silicone or some similar material to prevent rust from developing.
Finally, the remote wire needs to run to the power amplifier (or antenna remote) lead of the head unit. This wire supplies a 12 volt signal to the crossover when the main system is activated.Once you have routed the power, ground, and remote wires through the vehicle, it is time to connect the wires to the
FRX-456
. Be sure that you have not reconnected the
ground cable to the negative post of the battery. Cut off excess wire and, using wire strippers, strip the power, ground and remote cables
about 1/8 inch. Locate the power, ground, and remote
Powerlock
connector (supplied). On the top of the connector are three slotted screws.With a small flat-bladed screwdriver, loosen the screws before attempting to insert the cables. After you have inserted the stripped end of each cable into the connector, secure it b y tightening the associated scre w. Check that each connection is tight. If the wires are secure, the connector ma y be plugged into the
FRX-456
.

Caution! If you are using a source unit with bridged high powered (or "floating ground") speaker outputs, a suitable high to low level adapter must be used.We recommend the Directed Audio Essentials adapter p/n (55020). If you are unsure about your head unit see your local
PrecisionPower
dealer or call
1-800-62POWER.
To use Speaker Level Inputs (common ground headunits only), connect RCA plugs to the front or rear speaker leads as shown, and push IN the Attenuation switch.
