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.

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.

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. Drill 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.
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.
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.
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.
Connect the front RCAs from your head unit here.
4.Front Inputs-
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 by tightening the associated screw.
Check that each connection is tight. If the wires are secure, the connector may be plugged
into the FRX-456.
5. After connection-
After connecting Ground, Remote, and Power wires, plug in the
Powerlock connector here.
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.
