The 3000 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 supply is not up to these specifications, we recommend having it checked by
an automotive mechanic before you continue the installation.
RECOMMENDED POWER WIRE
The proper wire size is very important for an amplifier of this power level. Because the
3000 is capable of drawing in excess of 90 amperes, we recommend auge wire for
lengths up to twenty feet. If a longer length is needed, a larger gauge wire may be necessary.
POWER
All amplifiers 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. We
recommend the use of grommets when passing the power wire through any metal surface. 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 wires are connected.
GROUND
When grounding your amplifier, locate a metal area close to the amplifier that is a good source of
ground. 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 auge 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
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 to the
wire, back at the amplifier, loosen the set screw for the terminal marked REM on the amplifier using
a 3mm Allen 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.
