It’s also important to ensure the speaker wires are properly insulated to prevent any shorts that could damage your new audio equipment.
Power Wiring
The power wiring section of the diagram includes information on the wiring for the radio’s power source and the amplifier (if you have one). The power source wire connects directly to the battery or fuse box, while the amplifier power wire connects to the same power source wire.
Make sure you use the correct gauge wire for the power wiring to ensure proper power distribution and prevent any electrical issues.
Ground Wiring
The ground wiring section of the diagram provides information on the wiring for the radio’s ground wire and the amplifier’s ground wire (if you have one).
