Usually * the wire with the white stripe or the dashed lines carries the "positive" (+) end, while the other, unmarked wire carries the "negative" (-) end. If they are not visible, you can test it with a 9-Volt battery. Green (or with one Yellow stripe in some cases) is the earth grounds color in AC wiring. Here is the color coding for SAAB car speaker wires. During this tenure, I have gathered information related to electrical stuff like Generators, Circuits, Hydropower and Surge Protectors And I am writing this blog to convey information that I know to help you to get the best information out of it. The black speaker wire stripe denotes a negative signal. This is often where confusion can occur because the labeling isn't always obvious. It also provides a 12 volt power signal. The solid/dashed lines on wires like the ones pictured in your question are used to indicate polarity e.g. There are many free online tools available to determine polarity. Generally speaking as a trade standard most speaker wires with a white stripe are used as the positive wire. This test is important for determining whether or not a speaker wire is a positive or a negative one. Considerations when installing (pulling) in-wall speaker wire: Pull strength dont use excess force when pulling wire through the wall, Minimum Bend Radius do not create severe bends or 90 degree angles in speaker wire.

But again, dont expect every speaker to use a black/red wire combination. It is more important to maintain consistency. If the speaker wire is connected to the speaker, the stripe will be positive not negative. Other in-wall cables, such as doorbell wire and electrical wire (Romex) are made with electrical grade wire. However, the wires can harm your speaker system. Step 4. Its purpose is to carry an electrical signal (voltage and current) from the amplifier (or the amplifier section of a receiver) to the speakers. Speaker wire consists of equal numbers of electrical conductors insulated from each other surrounded by a protective jacket. So, make sure you know what exactly you're doing before jumping head first into buying any kind of wire! In most cases, red speaker wires are positive (for two-conductor speaker wires) and red and green (for four-conductor speaker wires, red for the left speaker, and green for the right speaker). We have documented everything about Smart Home Wiring and Speaker Wire here. Their only concern is consistency. Typically, wires are marked with a plus (+) or a minus (-) sign, but you can also identify unmarked wires by their color, texture, or appearance. You can always upgrade components later. Most in-wall whole house speaker cables are made by using multi-stranded conductors. Check the color - Black wire is negative, White is positive. This article explains how to identify car speaker wire colors when installing a car stereo. Inexpensive speaker cables are manufactured by connecting one + and one conductors in parallel. In general, speaker wires are black, but you can find red, white, or green ones as well.
