CONTROL FUNCTIONS
1. Speakers - Connect speakers/subwoofers to these terminals. Be sure to check wire for proper
polarity. Never connect the speaker cables to the chassis ground.
2. +BATT (+12 Volt Power) - Connect this terminal through a FUSE or CIRCUIT BREAKER to the
positive terminal of the vehicle battery or the positive terminal of an isolated audio system
battery.
WARNING:
Always protect this power cable by installing a fuse or circuit breaker of the
appropriate gauge within 18 inches (45cm) of the battery terminal connection.
3. Remote Turn On - This terminal turns on the amplifier when (+) 12 volt is applied to it. Connect it to
the remote turn on lead of the head unit or signal source.
4. GND - Run an equal gauge wire from the Ground (GND) terminal on the MTX amplifier to the
negative terminal on the battery. Use the shortest distance possible. It is always a good idea to
replace the factory ground at this time with a cable equal or larger than the new amplifier power
cable.
CAUTION:
Do not connect this terminal directly to the vehicle battery
ground terminal or any other factory ground points.
5. RCA Input Jacks - These RCA input jacks are for use with source units that have RCA outputs. A
source unit with a minimum level of 200mV is required for proper operation. The use of high
quality twisted pair cables is recommended to decrease the possibility of radiated noise entering
the
system.
6. Gain Control - The Gain control will match the amplifier’s sensitivity to the source units signal
voltage. The operating range is 5V to 200mV.
NOTE:
This is NOT a volume control.
