S ervice
Do not attempt to service PrecisionPower products yourself.
Performing exploratory surgery on your audio equipment yourself
will void the warranty. Many parts of your PrecisionPower gear
are custom built to our specifications. Our factory parts are not
made available to anyone else nor are they for sale. Our goal
is to make sure that your PrecisionPower product will always
sound as good as the day it was purchased. Contact your

INSTALLATION / MOUNTING
NOTE:
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.
Mounting
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 include the trunk and passenger
compartment (floor or under seat). Never mount the crossover
in a location that would subject it to immersion or exposure to
water.
Once a location has been chosen, securely mount the
EPX-223 with 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 bit or screws.

NOTE
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.

WIRING
The next step is to connect the Power, Ground, and Remote wires to
your EPX-223. 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. As
a rule of thumb, use as short a length of wire as possible.
Find a location near the crossover 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
Powerlock
prevent rust from developing.
Finally, the remote wire needs to
Remote
Power
Ground
run to the power antenna (or
amplifier remote) lead of the head
unit. This wire supplies a 12 volt
signal to the EPX-223 when the
T/O B+
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 EPX-223. 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
by tightening the associated screw. Check that each connection is
tight. If the wires are secure, the connector may be plugged into the
EPX-223.
