Product Information

You can splice 2 differently-sized wires together, as long as they're close in gauge (like 18AWG and 16AWG). To begin, follow the wire cutting & stripping steps from the first section (using crimp connectors).

Read on to learn more about these plus other options you have. How to splice wire with crimp connectors Examples of some of the best ways to cut speaker wire using tools or a pair of utility scissors. Cutting wire is easy with the correct tools. Many tools like wire strippers or crimpers also have a cutting feature built-in. 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? Scissors aren’t a good choice and the wire can even get jammed inside. 2. How to strip speaker wire This is hands-down the most reliable way to extend & splice speaker wire. When done properly soldered wire is extremely strong. How to solder speaker wireWhile you can get by with utility scissors (don’t use standard scissors used for paper or fabrics!) you’ll have to insert the wire right at the inside of the blades and cut very carefully. It’s important to fully cover the wire once you’re done. That’s to prevent the wire from touching each other and cause a short circuit that can permanently damage the output components in an amplifier or stereo. How long does soldering speaker wire properly take? 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

I recommend trying that as since the internal opening is a bit bigger you can be sure they’ll fit with various types of speaker wire near that size. That’s because speaker wire manufacturers sometimes have different internal wire conductor sizes. Splicing speaker wire by soldering Certain types of wire (especially smaller gauges like 20AWG, 24AWG, etc can be harder to strip without breaking. For your first few times, practice on some surplus wire that won’t hurt your speaker wire length needs. 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.

Crimp very hard with the tool to make press the connector down hard, holding the wire inside permanently.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. For crimp connectors, 3/8″ or more should be fine. 3. How to use crimp connectors with speaker wire
