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 import a nt for an amplifier of this power level. Beca u se the
Class "D" amplifier is capable of drawing in exces s of 90 amperes,4 gauge wir e 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 batt e ry using the wire requirements
listed above. Start at the amplifier and run the power wire through the vehicle to the
battery. The use of grom mets is recommended when passing the power wire through
any metal wall. Avoid sharp corne rs or sharp body parts that may easily cut through the
insulation on the wire. Avoid runn ing 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 you r
power wire. Connect the fuse holder as close to the batter y positive as possible. For
most applications, an 80 ampere Maxi fuse or comparable ANL wafer fuse can be us ed.
Now connect the wire to the batte ry, but remember to leave the fuse out unti l 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 gro und 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, sp read 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.
