POWER CONNECTIONS & SPEAKER OUTPUTS

1 2 3

The power and speaker connections for this amplifier are explained in the summaries below and reference the numbered call-outs above.

1.) 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 car, capable of handling high current loads and within 3 feet (absolutely no longer than 3 feet).

TRIGGER - This allows the amp to be remotely switched on from the radio and normally uses a dedicated “trigger” line output. If one is not available, simply use the power antenna line. When a +12 volt DC signal is applied it will turn on the amplifier.

+12V - A high current line run directly to the battery is required. This line should NOT be connected to the fuse block of the vehicle. It MUST be fused through its own dedicated fuse at the battery.

2.) 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 amplifier. Although another fuse is located at the battery, in line with the battery high current line, this fuse MUST remain in the circuit to physically protect the amplifier.

3.) SPEAKER OUTPUT CONNECTIONS - These connections are used to connect to the loudspeakers with the appropriate impedance. It is imperative that these lines NOT be connected or touch the chassis of the vehicle in any way. Also, the (+) and (-) leads are in no way inner connected so the left channel (+) and the right channel (+) must remain independent. In addition, the (-) leads for the speakers CANNOT touch or be wired to the ground lead of the amplifier; these are NOT common ground amplifiers.

Important

If wiring connections are made wrong, the unit will not operate properly and it could be damaged. Follow the installation instructions carefully, or have the installation handled by an experienced technician.
