Where can I find wiring diagrams for my car?
Every car follows its own color-coding system for wires. There is no standard or international system, so find the wiring diagram specific to your make and model in your owner manual. If you no longer have your manual, look for one in a library or online. Or, reach out to a mechanic at a local shop or dealership.
Is copper wire positive or negative?
Know that the copper wire is usually positive on a speaker wire. On a standard wire used for things like speakers and amps, the silver strand is the negative wire and the copper-colored strand is the positive wire. These wires are often held together by a clear casing, so they’re easy to determine the polarity of each side quickly.
What is the difference between a black and red wire?
If the multi-colored wire is black and red, the black wire is the negative wire, while the red one is positive. If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive.
