How do you wire a xovision with no wiring harness?

To wire a Xovision unit without a wiring harness, you'll need to connect the power and speaker wires directly. First, identify the power wires: connect the red wire to the positive supply and the black wire to the ground. Then, connect the speaker wires from the Xovision to the corresponding wires of your speakers, ensuring you match the positive and negative terminals. Finally, secure all connections with electrical tape or solder to prevent short circuits.
