For long wire runs the wire diameter must also increase. The wire sizes noted allow for a maximum 0.5 volts DC drop over the give wire run which results in Sound Pressure Level drops inaudible to the average listener.

The speaker wire chart shows the minimum recommended wire size for a single audio output channel driving a loudspeaker at a given distance with a maximum power loss of 0.5 dB, the threshold of audibility. (Wire sizes larger than those noted are usually a waste of time and money since they offer little or no performance improvements.)

This line should NOT be run to the fuse panel of the vehicle but directly to the battery. DO NOT Grommet run to the alternator either. There MUST be a fuse installed at To prevent damage to the battery with adequate amperage as shown in the chart power wire above. Power Wire (10 gauge wire or larger) As for the final signal wiring, be sure to route the audio cables down the side of the car opposite the power lines to avoid noise pick up from the lines. Also, try to route all audio cables away from noise sources such as engine computers and ABS brake computers. Proper power grounding is important to insure adequate current flow. Be sure to grind the surface clean of all paint to ensure a solid electrical connection. – 5 – Speaker Wires or RCA Cables Speakers Amplifier Ground Screw Drill 1/8” hole in chassis sheet metal Use the same ground if using multiple amplifiers Power Antenna Turn-On Wire (18-20 gauge wire) Radio Battery Fuse or Circuit Breaker CONNECTIONS & CONTROLS Speaker Outputs Ground +12 (Battery) Trigger Fuse 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. 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.
