Power Supply Connections

The Class "D" amplifier is designed to work within 10 to 16 volts DC. Before any wires are connected, the vehicle's electrical system should be checked for correct voltage supply with the help of a voltmeter. First check the voltage at the battery terminals with the ignition in the off position. The voltmeter should read no less than 12 volts. Next, check the battery with the engine running between 1500 and 2000 rpm. The voltmeter should now read between 13.5 and 14.5 volts. If your vehicle's electrical system Is not up to these specifications, we recommend having it checked by an automotive mechanic before further installation.

RECOMMENDED POWER WIRE

The proper wire size is very important for an amplifier of this power level. Because the Class "D" amplifier is capable of drawing in exces of 90 amperes,4 gauge wire is recommended for lengths up to twenty feet. if a longer length is needed, a larger gauge wire may be necessary.

POWER

Amplifier power wire should be wired directly to the battery using the wire requirements listed above. Start at the amplifier and run the power wire through the vehicle to the battery. The use of grommets is recommended when passing the power wire through any metal wall. Avoid sharp corners or sharp body parts that may easily cut through the insulation on the wire. Avoid running the power wire over engine components and near heater cores. Use an inline fuse to eliminate the risk of a fire caused by a short in your power wire. Connect the fuse holder as close to the battery positive as possible. For most applications, an 80 ampere Maxi fuse or comparable ANL wafer fuse can be used. Now connect the wire to the battery, but remember to leave the fuse out until all other wire connections are mode.

GROUND

When grounding your amplifier, locate a metal area close to the amplifier that is a good source of ground ( preferably the floor ).Once again, investigate the area you wish to use for electrical wires, vacuum lines, and brake or fuel lines. Using either a wire brush or sandpaper eliminate unwanted paint to supply a better contact for your ground. Use the same gauge wire for ground as you did for the power. Terminate the ground wire using the correct size ring terminal and attach it to the bare metal using a nut and bolt. It is important for this connection to be solid. To complete the job, spread silicon over the screw and bare metal to prevent rust and possible water leaks.

REMOTE TURN-ON

In between the power and ground is a remote turn-on terminal. This terminal must be connected to a switched +12volt source. Typically, remote turn-on leads are provided at the source unit that will turn on and off the amplifier in correspondence with the source. If a radio does not have a remote turn-on, then a power antenna wire may be used. Yet, if neither of these leads are available at the source, a switched +12 volt supply must be supplied. Run a minimum of 18-gauge wire from the amplifier location to the source of the switched +12 volt lead. If possible, route this wire on the same side of the vehicle as your power wire. Connect the source remote output wire to the REM terminal on the amplifier using a 3mm screw key. Cut the remote wire to length. Strip approximately 1/2 inch of insulation from the end of the wire and insert into the terminal. Tighten the screw securely.
