Output & power supply connector
1 - OUTPUT: To connect the speakers. Follow the polarity and the minimum impedance
recommended.
For STEREO connections, the minimum impedance is 2 ohms at each channel; for BRIGDED
connections is 4 ohms.
To combine speakers, the resulting impedance must be taken in consideration.
See the examples below:
2 - POWER (Power Supply Connector): The connector terminal (+) must be connected to the
battery's positive pole with a 5 AWG (16mm²) minimum wire gauge. The connector terminal (-
) must be properly connect to the battery's negative pole with a same wire gauge. The remote
terminal must be connected to the Head Unit REMOTE output with a 18 AWG (0.75mm²) wire.
Protection system
Short-circuit Protection: Shutdown the amplifier when detect a short- circuit or impedance
lower than the supported at the output.
High / Low Power Supply Voltage: If the supply voltage is below 9V or above 16V, the
protection system will trigger by cutting off the audio signal. (See page 03 - LED indicator).
NOTE: Impedances lower than that supported on output may cause short-acting protection. Likewise, excessive
distortion of the signal also triggers an internal protection system, resulting in the shutdown of the device. In this
case, turn off the amplifier level attenuator and turn it on again.
