This article explains how to splice speaker wires using electrical crimp connectors.
Before you start splicing, properly set up the speakers and equipment. Turn off the power to the home stereo receiver and disconnect the power cords. Unplug and examine all speaker wires, then set them aside for later use. Any that appear damaged or in poor condition should be thrown out.
Now you're free to move speakers to their new locations. Time permitting, this can be a great opportunity to consider how you might hide or disguise speaker wire in living areas. With the proper techniques, wires can be put safely and aesthetically out of sight.
After the speakers have been placed, determine the length of wire required to connect each speaker to the stereo system. Use the measuring tape and tally the distances. It's better to overestimate slightly than underestimate, as slack is easy to manage, and splicing involves a bit of trimming anyway.
Write down the numbers along with the speaker location (for example, front left/right, center, or surround left/right) in a notepad. When finished, measure the speaker wire you set aside earlier and compare it to your notes. There's a chance that some of those wires will be the right length. Also, double-check that the wires are the proper gauge.
If you have wires that don't need splicing, label them with the assigned speaker and set them aside. Cross those speakers off your notes so that you know they've been accounted for.
Choose any remaining wire and assign it to a speaker with a label. Calculate the difference between the length of wire you have versus what the speaker needs. This is how much you'll cut from the spool of speaker wire. Give yourself an extra inch or so and make the cut using the wire strippers. Label the pairs of wires, set them aside, and cross the speaker off your notes. Repeat this process with any remaining speakers on the list.
Take one set of wires that you intend to splice and place the ends/terminals next to each other—negative to negative (-), positive to positive (+). You want the wires to be in-phase. If you're unsure, test the speaker wires with a battery. Using the wire cutters, strip off the exterior jacket/insulation so that all four ends have a quarter-inch of exposed copper wire. You can separate the individual wires (positive and negative terminals) by an inch, so you have room to work with them.
Take both negative ends of bare wire and insert them into opposite sides of a crimp connector. (Double-check that it matches the gauge.) Using the crimping section of the wire cutters (it should be marked so that you correctly match the gauge), firmly squeeze the connector so that the connector's metal tubing shuts close around one of the bare wires. Do this once more for the other bare wire.
After attaching the crimp connectors to the positive and negative wire ends, gently apply a heat source to shrink the connectors. A hot air gun or a blow dryer set to high heat is best (held a few inches away), but you can use a lighter if you’re extremely careful and hold the lighter at least an inch away.
Hold the wires with your offhand (a few inches below the crimp connections) as you apply the heat. Slowly rotate the wires/connectors so that you get around all sides. The crimp casings will shrink snug against the speaker wire, creating a protective and waterproof seal. Some electrical crimp connectors are designed with a bit of solder on the inside, which melts from the heat and fuses the wires for a stronger connection.
Now that you've spliced the wire, the last thing to do is connect the speakers to the stereo receiver/amplifier or home theater system. Before starting, consider installing speaker wire connectors (for example, a pin, spade, or banana plug). This is the best time to do it because you have the tools and wires right there. Speaker wire connectors make plugging into spring clips or binding posts a breeze.
Once you're done, test the stereo system to make sure that the speakers work properly. Double-check the speaker/receiver connections on any that are not.
Rearranging living areas is a great way to open up space, but it may mean relocating speakers and home theater equipment. You could cut and install new speaker wire, but why toss out functional wire when splicing gains the extra feet without the waste?
There are a couple of ways to splice speaker wires. One way is to twist speaker wires together and use electrical tape. However, tape wears out over time, and the smallest tug on the wires can separate the connection.
The better option is an in-line electrical crimp connector (also known as a "butt" connector). Crimp connectors are durable, easy to use, and effective. Plus, most provide a weatherproof seal, which is desirable when installing outdoor speakers. Still, crimp connectors are meant for stranded speaker wire—not solid core wire. Here's what you'll need to get started:
•Spool of speaker wire (matching the gauge of the existing wire)
Dec 13, 2023 · The splice speaker wire technique is employed in various scenarios, ranging from customizing audio setups to extending speaker cables for optimal placement. This technique can not only raise your technical level but can also help optimize your system in certain cases.
Feb 11, 2024 · Why Splice Speaker Wires? There are a few reasons you may need to splice speaker wires. The main one is you need a longer speaker wire from two or more wires. It’s important however that you consider the gauge of the wires and the length because speaker wire length can affect audio quality.
Mar 21, 2004 · I do it for short speaker runs from my amp to a wall panel. Having a RCA connector at the wall panel uses less space than a couple of banana plugs. You could use the speaker wire for a line-level run to your sub, but it may be subject to RF interference. You're better off using shielded coax.
Sep 10, 2003 · I cut that in half (it appears to have a part of it shielded, why?), and spliced it with some speaker wire, both channels mushed into one. (Should that make a difference?).
Aug 2, 2007 · So if there is ever a problem in the future where that cable is involved, the splice point is the first thing to check. As far as how to accomplish a splice, there are several methods, all with their own specific strength and weaknesses. We'll fully explore each of them. Twist and tape.
