Stranded wire right is tremendously easier to deal with. Stranded wire is made up of a large number of tiny copper wire strands, making it very flexible and also easier to strip, crimp to connectors, and work with by hand.
Solid wire, however, has only one conductor. Solid wire is a terrible choice for nearly all audio systems and especially car audio installations. But why? Over time, the wire can develop weak spots which break!
Measure the distance and then add a few feet 2 or so is good to account for little differences. A tape measure works well and so does string or rope you can place along the path where the wire will go. Mark the length, then measure it. I like to add at least 1 foot of length for each wire section for home stereo use and 2 feet each for car stereo installations to play it safe.
When it comes to buying speaker wire, one thing to know is that it adds up fast! Here are two examples to show what I mean:. Car stereo example: Running wire from the dashboard head unit to front door speakers and to rear deck speakers.
Speaker wire is normally sold in rolls such as 25ft, 50ft, and ft, although some retailers offer it by the foot as well. Precut lengths are also available sometimes, too. Those are usually around 6, 12, or 18 ft. Buy at least a little bit more than your estimate. The most common kinds of positive wire markings are shown here as examples. 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.
However, as a rule the copper wire is treated as the positive. Once you know which is the positive wire then the other is the negative wire. We use one wire as the positive one when connecting speakers to be consistent when connecting them. Wire cutting pliers are very handy for cutting small to large wire. Automatic wire strippers make stripping wire super easy. There are a number of affordable tools for cutting or stripping speaker wire.

Relative thickness of wire gauges, drawn to scale not actual size. Pull 4-conductor wire to an in-wall volume control left or a stereo-input speaker right. Spring clip terminals accept bare wire or pin connectors.
Looking for speaker wire? To get the best energy transfer a thicker wire such as a gauge wire would be preferred over an gauge thinner wire. Your decision should also be based on the length of the cable run and the impedance, or power requirements of your speakers. Measure the distance from the amplifier to each speaker in the system and make sure to include approximately 4 to 6 feet of extra cable slack at each end.
If your speaker has a nominal impedance of 4 ohms or lower and it requires a lot of power, so it is best to choose a 14 or gauge wire, despite the distance.
For most 8-ohm speaker circuits with a shorter than 50 feet run, a gauge wire would be an ideal choice. For wire runs beyond 75 feet, choose at least 16 gauge, if not a 14 or gauge wire. At this longer distance, the resistance of the cable will be increased considerably, so you will want to keep the resistance of the cable as low as possible with a thicker gauge wire.
