Wiring

Important notes on wiring:

• Refer to the "Installation Precautions" section.
• Disconnect the negative terminal of the vehicle battery prior to wiring.
• Connect the unit to a 12V DC battery with a negative ground only.

The unit has the following connections:

• AUX IN: For audio input via 3.5mm jack.
• MAIN OUT: For audio output, typically via RCA cables.
• REMOTE OUT: Blue wire for amplifier turn-on signal.
• GROUND-: Black wire for ground connection.
• POWER+: Red wire for power connection.
• ATM fuse (2A): Integrated fuse for protection.

Optional direct battery wiring circuit: This circuit involves connecting the unit directly to the battery via a fuse holder (5A recommended) and an optional on-off switch, with a chassis ground connection.

Connection Details:

• A (MAIN OUT): Use RCA cables (not included) to connect the MAIN OUT sockets to the RCA input on a 12V amplifier (not included) for sound output.
• B (REMOTE OUT): Use an 18-gauge wire (not included) to connect the blue REMOTE OUT wire to the remote terminal on the amplifier. This controls the amplifier's turn-on/turn-off.
• C (GROUND): Use an 18-gauge wire to connect the black GROUND wire to the metal frame (chassis) of your vehicle.
• D (POWER): Use an 18-gauge wire to connect the red POWER wire to the battery's positive terminal. It is recommended to connect the battery through a 5A fuse (not included) and an on-off switch (not included).
