MAKING THE CONNECTIONS
POWER CONNECTIONS
Use
Source Unit
Connect the source unit’s remote
any convenient gauge wire for the connection.
The amplifier’s internal neon lights require a separate switched power connection with at least a

SIGNAL CONNECTIONS
Use
connect its signal to both input jacks.
As a convenience, each JBL A6000GTi or A3000GTi amplifier is also equipped with a set of
REMOTE LEVEL
For gauges, varying voltages are output on selected RJ45 pins to indicate voltage, current and temperature.
For battery voltage, linear scale (pin 1): 2 volts = 8 volts at the battery
4.5volts = 18 volts at the battery For temperature, linear scale (pin 2):
0 volts =
5 volts = 110 degrees Celsius For current, linear scale (pin 3):
0 volts = 0 amperes current draw
5 volts = 800 amperes current draw
Also, you can connect a power meter using the pins for battery voltage and current. Be sure to use a power meter that multiplies the incoming voltage and

(Bare Metal)
The A6000GTi and A3000GTi use an RJ45 connector to output control signals for the Remote Level Control and accessory gauges. Use the 15' RJ11 cable to connect the control to the amplifier. For accessory gauges, use the pinouts in Figure 6 to make custom cables with materials found
at most electronics supply stores or home centers.

CONNECTING
THE SPEAKERS
IMPORTANT: As a safety feature and due to the high output voltage capability of the A6000GTi and A3000GTi amplifiers, the SPEAKER OUTPUTS are equipped with a cover that must be in place in order for the amplifier to operate. When the cover is removed, the amplifier will turn off and speaker connections can be made safely.

IMPORTANT: Do not connect a jumper directly between the REMOTE and LIGHTING terminals. Doing so may burn out the remote
in your source unit.
