Is it OK to splice speaker cable?

Splicing your speaker cables can be an incredibly effective way to extend the length of your cable runs. If it’s done well, you really shouldn’t notice any difference in your audio playback. If it’s done poorly, however, it can lead to audio dropouts and even short circuits.

Can I cut speaker wire to extend it?

You’ll need a little extra slack in the wire, since too much tension could damage the connection on your speakers or amp or cause the wire to pull free. Then, use wire cutters to cut the extra speaker wire to that length. Many wire strippers also act as wire cutters, so you may not need two separate tools for this.

Can you connect 2 speaker wires together?

Summary of Connecting 2 speakers

If each speaker has an impedance of 8 ohms or more, then you can generally connect them in parallel. If each speaker has an impedance below 8 ohms, you should wire them in series.

How do you join a broken speaker wire?

How To Solder Wires | Repair Broken Speakers

What is the best way to extend speaker wire?

Using a Wire Cap

One of the easiest ways of splicing a wire is using a twist-on wire cap. Simply put the two wires you would like to splice side-by-side facing the same direction. Affix the cap to the ends of the wires and twist clockwise to tighten the wires together.

Is it better to solder or crimp speaker wires?

Crimping offers stronger, more reliable connections than soldering. Soldering uses heated metal to join the cable to the connector. Over time, this filler metal will degrade, which may cause the connection to fail. Most electricians will agree that crimping is also easier than soldering.

Does the length of speaker wire affect sound?

When long runs (of either interconnects or speaker cables) are used, cable quality becomes extra important. Due to the additional signal losses longer runs impose, the better the cable is at “protecting” the signal, the better will be the sound.

Is thicker speaker wire better?

When determining which wire gauge to use, consider how far away the speakers are from your amplifier or A/V receiver. Generally, for short speaker wire runs, a 16-gauge wire is sufficient. However, for longer speaker wire runs (to another room, for example), it is better to use a thicker, lower-gauge wire.

How long is too long for speaker wire?

Note2: Avoid Speaker Cable runs more than 50 feet. Best Performance can be achieved by moving the amplifiers closer to the speakers. For example, 18 gauge wire connected to an 8 Ohms speaker should not exceed more than 32 feet in length from amp/receiver to speaker.

Are speakers louder in series or parallel?

Speakers are always louder when wired in parallel. Series wiring leads to more impedance and thus less voltage per speaker which translates to less volume per speaker. A parallel circuit reduces the resistance and impedance on each speaker and equates to more volume.

How do you couple speaker wires?

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).

Can you use 4 conductor speaker wire for 2 speakers?

Yes, you can use 4 conductor speaker wire to connect a pair of speakers that each only have 1 pair of connections.

How can I extend my speaker wire without cutting it?

Make sure that the cables you want to connect have the same cross section size (more info below). Turn the ends of the stripped cables counterclockwise. Then all the cable threads should be together. Now connect the two cable ends with each other, either by soldering and shrink tubing or with a luster clamp.

How do you connect speaker wires without soldering?

What you need: a roll of electrical tape and two wires whose ends have been twisted together. First, lay the twisted part of the wires onto a strip of electrical tape. Wrap the tape around the wires tightly 5-6 times, making sure to cover up all the wire. Give your connection a tug to make sure it is strong.

What glue is best for speaker repair?

Epoxy adhesives, in particular, are suited perfectly to assemble and repair speakers. Epoxies are able to handle the high temperatures and extreme stresses created by the coil and magnet in a speaker.

What is the maximum distance of speaker wire?

While in theory heavier wire can have longer runs, recommended household audio lengths should not exceed 50 feet (15 m). The gauge numbers in SWG (standard wire gauge) and AWG (American wire gauge) reduce as the wire gets larger.

Does it matter which way around speaker wires go?

It doesn’t matter which way round you connect the wires – even if the wire is marked with a plus and a minus. Just make sure that the same piece of wire is connecting the positive and negative terminals on the amplifier and speaker.

How do you extend existing wire?

Dealing With Electrical Wires That Are Too Short

Does it matter red or black speaker wire?

typically, the positive wire is red and the ground, or negative, is black. However, most speaker wires don’t do colors. Good news is, with speakers it doesn’t really matter which one you choose as your positive and which as your negative, just so long as you are consistent.

Is bare speaker wire better than banana plugs?

Not only do they help your installation to look cleaner, banana plugs also give you a permanent and high quality connection. Often bare speaker wire connections are unreliable. Wires tend to get pulled out or frizzy as time passes, which can affect your sound quality.

Is solid wire better for speakers?

For example, a 12 AWG is thicker than an 18 AWG wire. The most common audio speaker wires are 12 Gauge, 14 Gauge, 16 Gauge, and 18 Gauge. Stranded wire is more flexible, easier to route, can withstand vibration and flexing than solid wire; therefore, it is more commonly used in audio speaking wiring.

Is silver speaker wire better than copper?

While copper tends to sound warmer and has more body it is a bit slower and less harmonically rich, silver does exactly the opposite. Silver tends to sound livelier, while offering more clarity and harmonic richness but at the cost of a colder character, thinner and lighter body.

What is the best wire for speakers?

For the best quality wire, looking for something made with 100% copper is highly recommended. However, if you’re looking to save a bit, copper-plated or copper-clad aluminum wire is a fine substitute, and there is no noticeable difference in sound quality.

What gauge wire is best for subwoofers?

The speaker wires. If your sub system is going to put out more than 1,000 watts RMS, you can use 12-gauge speaker wire. But 16-gauge speaker wire works well for most installations.

Is 12 gauge speaker wire overkill?

Thick wire (12 or 14 gauge) is recommended for long wire runs, high power applications, and low-impedance speakers (4 or 6 ohms). For relatively short runs (less than 50 feet) to 8 ohm speakers, 16 gauge wire will usually do just fine.

When should I use 12 gauge or 14 gauge speaker wire?


What happens if your speaker wire is too thin?

Using thin wire over too long a distance will result in a reduction of power to your speakers. Worse, if the wire is too thin for the amount of current it is trying to handle, it might melt, causing damage to the amplifier.

How far can you run 12 gauge speaker wire?

Speaker wire of 14 gauge is good for an 80-foot run, and 12 gauge is good for 120 feet.

What gauge wire for a 1000 watt amp?


Amp Kit AWG (Wire Size)Amplifier Wattage
1/0 AWG1000 Watts RMS and up
4 AWG500 – 1000 Watts RMS
8 AWG250 – 500 Watts RMS
10 AWGLess Than 250 Watts RMS

Do speaker cables need to be burned?

A: Minimally, you should burn-in your new cables when they are first purchased. However, if cables are left unused for a prolonged period of time they become stagnant and should be reconditioned accordingly.

Is it OK to twist speaker wires together?

For the connection to the speakers it’s fine, for connecting audio sources to the amp’s input it’s not. Both shielding and twisting’s purpose is to keep noise from your signal.

Can clipping ruin speakers?

Facts about clipping: Any clipped signal can potentially damage a speaker. It does not matter whether the mixer, amplifier, or any other piece of audio equipment clips the signal in the system. Damage can occur even when the amplifier is not at full output.

What will happen if speaker wires are crossed?

When the wires from the amplifier to the speaker are crossed, the speaker polarity will be inverted. This means that the speaker will move inward when it is supposed to move outward, and outward when it is supposed to move inward.

How can I extend my speaker wire without cutting it?

Make sure that the cables you want to connect have the same cross section size (more info below). Turn the ends of the stripped cables counterclockwise. Then all the cable threads should be together. Now connect the two cable ends with each other, either by soldering and shrink tubing or with a luster clamp.
