Mounting

MOUNTING

To prevent damage to the

PAR-245

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

PAR-245

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

P AR-245

using the two supplied brackets. There are two different sets of brackets included with your

245

, as shown above. The other set is used to surface mount, as

P AR-245

. One set is used to flush mount the

P AR-

shown on the next page. The brackets are connected to the equalizer/ preamp by two 6-32 x 1/4" socket head cap screws. We have made the brackets adjustable to compensate for the uniqueness of each vehicle. Be Careful! Inspect the area underneath to be sure you are not drilling into wires, 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 ,"

"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

PAR-245

. 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 equalizer 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. Finally, the remote wire needs to run to the power antenna (or

Ground

Remote

amplifier remote) lead of the head unit. This wire supplies a 12 volt signal to the

PAR-245

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

PAR-245

. 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
