Hold both ends and tightly twist each end around the other until they’re completely wrapped over each other. It also leaves behind an adhesive residue if it has been subjected to a lot of heat as often happens in car audio installations. Which speaker wire is positive? Which is negative?

Once you’ve prepared your speaker wire by stripping it, it’s time to use a crimp connector on each wire and a tool to crimp them for a reliable connection.

You’ll only need a few tools to do it. Between the two ways, using solder is extremely reliable but more hassle & takes more time. Crimp connectors, however, give great results in only minutes and this approach is what I use most of the time for my home or car installation jobs. To begin, follow the wire cutting & stripping steps from the first section (using crimp connectors).

Of the 5 listed here, I recommend and use wire cutting pliers as they’re capable of cutting a wide range of wire sizes. For typical speaker wire like 18 gauge, the wire cutting feature on many other tools works fine. The most common kinds of positive wire markings are shown here as examples. 99% of the time, figuring out which wire is positive is really easy once you know what to look for. Of the 5 kinds, imprints can occasionally be a little bit harder to notice so sometimes you need to look very closely under good lighting. Also, positive wires that use a “+” print can be a little hard to read sometimes, too. Which is positive: copper or silver? Insert the wire in the stripper and close it carefully on the insulation. Use enough force to hold the wire in place and slightly pinch the insulation, but not enough to put force on the wire inside.Speaker cable is the wire used for the electrical connections between speakers and amplifier sources. It has three key electrical properties: resistance, capacitance and inductance. Resistance is by far the most important property to look at. Low-resistance wire allows more of the source’s power through to the speaker coil, meaning more power and more sound. Simple enough. They’re pretty fast, but unfortunately, on occasion, I’ve seen them come loose from wire so I don’t advise using them. Instead, I’d highly recommend crimp connectors. Why you shouldn’t do it the “just twist and tape” way
