Speaker is an audio device that meets the needs of listening to your favorite songs. However, you have a problem with the speaker wire being too short or you placing it in a position where the speaker wire cannot reach the proper power source. In addition, the broken speaker wire is also the reason you should have an extending speaker wire. Refer to our article to know how to wire the speaker properly and the notes when doing it. Get started now!
1. Necessary items before extending speaker wire
Before you start wiring your speakers, you’ll need the necessary supplies to support them.
- Some tools you need such as wire cutters, screwdrivers, soldering irons, small knives, …
- The materials and equipment you need such as single-core speaker wire, wiring nuts, sandpaper, black insulating tape,…
2. Extending Speaker Wire
Extending Speaker Wire has 1 straight core
There are several types of speaker wiring for single-core wires, but the easiest way to make and achieve a strong connection is to solder the wires. You start with pliers or a small knife to cut the outer insulating sheath, then twist the 2 positive ends of each wire together.
Note that the positive side of the wire can be red and the negative side can be gold/silver.
Place the bare ends of each positive wire on top of each other to form an X. Then, turn one side of the cord toward you and the other end away from you to twist the two strings together. Continue twisting until the wires are firmly connected to each other. The last thing you need to do is tie the ends of the wires neatly and then glue the tape around the connection.
Applicable to speaker wires that need to be connected with a large length because this connection will not cause signal loss.
Extending Speaker Wire has a multi-fiber core
On the market there are also many speaker cables with cores from 1 to 3-4 cores because of its structure and sound transmission properties. And you also perform simple movements to remove the insulating shell as above. First you need to peel off the insulation of the conductor so that you can see the copper core inside, then you need to clean the sheath.
When the separation is complete, you let these cores wrap the cage together. After doing the above two steps, the next step you just need to twist from 3 to 4 turns in turn so that the inner cores connect together, the tighter you tighten, the more stable the connection will be.
The final step is always to double check the steps above to see if they are correct, the joints are connected and twisted together, so it should always be checked again when you’ve done it. Finish the steps above.
Extending Speaker Wire has a branching core
This is a type of wiring few people do, but if you need it for anything, it’s pretty handy. Remove the outer sheath so that the core has a long distance to facilitate connection, to avoid missing wires or loose wires. Next, you just need to put the 2 wires at right angles to each other and then take one wire and wrap the other wire and tie it firmly.
Note that if wrapping the ring is too difficult, you can use pliers to secure it. When connecting like this, surely the impedance and RMS power of the whole system will change, you need to calculate it properly otherwise it will lead to speaker and amplifier fire. Because this is also one of the difficult speaker wiring styles to do. Besides, Extending Speaker Wire with multiple fibers is similar to how it is done with a single-strand speaker wire.
3. Questions when extending speaker wire
How long should the speaker wire be?
The speaker wire is as long as you can, it is important that you use the right type of wire specifically for the speaker wire and speaker placement. The long speaker wires are used for factory sound systems, announcements, you should calculate the amp power so that it is reasonable, because the signal attenuation on the long wires is there and is usually relatively large.
Is it safe to extend the speaker wire with insulating tape?
This is a simple, easy to do and safe way to do it. While it may not be the safest way to wire two speaker cables, it should work. Make sure you don’t pull them too tight or too hard as they could come apart. Furthermore, you should also not have too high a voltage in your stereo system to avoid electric shock.
Wiring the wrong speaker wire will burn?
The answer is not to burn out if you just messed up the red and black wires. For example, the red wire of your amplifier is connected to the black pole on the karaoke speaker. But if you short the two speaker wires together, it will definitely burn the amp if the amp does not have a fuse, or there is no self-cutting circuit.
How to detect that you are connecting the wrong speaker wire?
Every time you turn on the speaker system and the amp gets abnormally hot, or only sings for a short time, the amp automatically turns off. The cause of this phenomenon is 98% due to the wrong polarity of the speaker wire or shorting the two terminals together.
Above are some common speaker wiring patterns and questions related to this implementation. There are several ways to wire speakers like you can twist the wires together and use insulating tape to secure them. But this insulating tape will wear down over time and with just a slight pull, the joint can easily come apart. And while the twist knots may be sturdier, they aren’t very aesthetically pleasing when used with home audio equipment. We hope that after you finish reading, you can know more about extending speaker wire. Get the tools you need to do it!
