How do you find a bad connection in a speaker wire?

To find a bad connection in a speaker wire, start by visually inspecting the wire for any visible damage, fraying, or corrosion at the connectors. Next, use a multimeter to check for continuity by placing the probes on each end of the wire; a lack of continuity indicates a break. Additionally, you can swap out the wire with a known good one to see if the issue persists, which will help confirm if the wire is the problem. If the issue continues, the problem may lie with the speaker or amplifier instead.
