POWER CONNECTIONS:

GROUND - This is the high current ground connection to the chassis of the car. It should be fastened to a clean ground connection in the vehicle, capable of handling high current loads. This wire should be no longer than 3 feet (1 meter)

+12v - A high current line run direct from the batter is highly recommended to insure adequate current and voltage. This line MUST be run through a dedicated fuse of some kind and this fuse should be located immediately next to the power source. This in-line fuse is used to protect the vehicle should a short to chassis occur.

TRIGGER - This line tells the amp to turn on and is remotely switched from the radio which normally provides an amp “trigger” output. This line is required to go “high” (+12V) to turn on the amp. If this line is not available, use the power antenna line trigger which is normally available in most radios.

FUSE - This fuse is only for catastrophic situations should the amplifier begin to self-destruct or incur installation situations where gross amounts of current are being required from the amp beyond its design limits. Although another fuse should be installed inline with the high power line at the battery, this amplifier mounted fuse MUST remain in the circuit to protect the amplifier.

Power Terminal (+12V)

Connect directly to the vehicle battery (+) terminal with 10 gage wire (minimum)

Ground Terminal

Connect to a good chassis ground. The ground connection should be clean, unpainted metal to provide a good electrical connection.

SPEAKER OUTPUTS - The amplifier is connected to appropriate impedance speakers via these leads. It is IMPERATIVE that these leads NOT be connected or touch the vehicle chassis in any way or the amplifier will be damaged. The (+) and (-) leads of the amp are in no way inter-connected to one another. Also, NONE of the leads can touch each other, touch ground, or touch +12V or damage may occur to the amp or vehicle.
