Precision Power G41810 manual Attenuation

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-456that 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.

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 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.

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.
