POWER WIRING AND SIGNAL CONNECTIONS
POWER CONNECTION
BATT+
The amplifier should be wired directly to the vehicle battery using a 8ga power cable. Start
at the vehicle battery and run the power cable through the vehicle’s firewall using grommets to the
amplifier’s BATT + screw terminal. If factory grommets are not available install grommets yourself to
protect the cable from sharp metal edges.
Avoid running the power cable over the engine components and near heater cores. The use of an in-
line fuse or circuit breaker is a must, this will prevent the risk of potential fire caused by a short in the
power cable. Connect the fuse holder or circuit breaker as close to the battery positive (+) terminal as
possible (no farther than 18-inches from the battery).
The fuse or breaker amperage should be no greater than the fuse rating found on the amplifier control
panel located on the side of the RTA enclosure. You can now connect the cable to the battery, but
remember to leave the fuse out or the circuit breaker “off” until the other cable connections are made.
It is highly recommended that the cable end connecting to the amplifier is terminated with a spade or
ring terminal.
IMPORTANT—You MUST install a fuse holder with an appropriate fuse in line with the power cable
no further than 18-inches from the battery.
REM
Run 18ga wire (not included) to the radio power antenna lead or remote output. This wire is
responsible for turning the amplifier on and off. If the source unit (radio) is not equipped with a Remote
lead you can connect this wire to an accessory or ignition point at the vehicle fuse block. In this type
of installation, the amplifier will be on whenever the ignition is on.
GND
A cable of the same size (gauge) as the power cable should be used to ground the amplifier.
Connect the ground wire from the screw terminal marked GND on the amplifier control panel to the
nearest bare-metal surface on the vehicle. Keep the length of the ground cable to an absolute mini-
mum using a spade terminal at the amplifier end and ring terminal as shown in below at the chassis
end (Fig 3).
