Your equipment will not be damaged. The worst thing that will happen is that it will not work well acoustically with properly wired speakers.

Which wire is hot if both are black?

Here’s a rundown of electrical wires: The black wire is the “hot” wire, which carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, which takes any unused electricity and current and sends them back to the breaker panel.

What happens if the neutral wire is not connected?

With a regular 120-volt AC circuit, the neutral wire provides a return path to earth ground. If the neutral wire disconnects, it would stop the flow of the electricity and break the circuit. The role of the neutral wire is to provide this path to the electrical panel to complete the circuit.

What happens if you mix black and white wires?
