POWER HOOK-UPS
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 therefore be checked for correct voltage
supply with the help of a voltmeter. First check the voltage at the battery with the ignition
in the o position. The voltmeter should read n o 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 le vel. Because of the
Class „D" circuit and the high output electric currents of more than 300 A can occour.
We recommend a minimum wire cross-section of 50mm per co nnection. ALWAYS USE
THE SAME THICKNESS OF WIRES FOR PLUS AND MINUS CABLE! Lead plus and minus
cable diectly to the power source.
POWER
Amplifier power wire should be wired directly to the battery usinf the installation requirements.
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 cut through the insulation of the cable. Avoid running the
wire over engine components or near heater cores. Use an inline fuse to minimalize the risk
of re caused by a short! 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 made.
GROUNDING
When grounding your amplifier locate a metal area inside the car, preferably close to the
amplifier. (floor) Once again, investigate the area you wish to use for electrical wires, watch
out for vacuum lines, brake- or fuel lines. Remove unneccessary paint to ensure a better metal
contact. Use the same wire for grounding as you did for power. Terminate the ground wire
and connect it directly to the metal. Therefore you use a nut. It is important that this
connection is stable. At the end you spread silicone over the screw and bare metal to prevent
rust and water leaks.
WE RECOMMEND TO CONNECT THE MINUS WIRE DIRECTLY TO THE BATTERY BECAUSE
OF THE HIGH POWER RUNNING
