11. What Type of Wire Should I Use Outside?
If you are using standard outdoor speakers, any of the wire we recommend or sell on our site will do for this application. If you are running this wire for more than 100 feet, you might want to insure you use 14 gauge wire in order to maintain a good signal.
If you are using 'garden' or 'rock' style speakers that require hidden underground wiring, we recommend you use 'direct burial' wire. This type of wire is designed to withstand the elements, and more directly, the heat of decomposing organics which would melt the coating of traditional wiring.
12. How deep should we bury the speaker wire? Could animals chew the burial cable or some insects infest it?"
We recommend burying speaker wire at least four to six inches. This has been the industry “standard” for years, and in all that time we have never had any reports of wild animals chewing or piercing the outdoor speaker cable nor any type of insect infestation.
13. What Gauge of Wire Should I Use?
For in wall or in ceiling speakers, for runs up to 100 feet for background music, you should use 16 gauge wire. Most homes under 2500 square feet would do fine if they are pre-wired with 16 gauge wire. For distances exceeding 100 feet, you should use 14 gauge wire. Please note that Gauges of wire are measured inversely. For instance, a 22 gauge speaker wire is very small; as a 12 gauge speaker wire would be large. Most of today’s consumer electronics accept 14 gauge wire. Some high end equipment accepts 10 gauge wire.
14. What is Impedance Matching?
On average, most home speakers have an impedance of 8 ohms. An Ohm unit measures levels of resistance. Resistance in a speaker varies based on the frequency it is using. A stereo receiver can operate speakers with total impedance of 4 ohms or more, depending on the quality of the receiver. Some common examples are as follows:
2 - 8 ohm speakers together in parallel = 4 ohms
3 - 8 ohm speakers together in parallel = 2.67 ohms
4 - 8 ohm speakers together in parallel = 2 ohms
Impedance matching can be easily achieved by adding a speaker selector or impedance matching volume controls to your new sound system.
15. Can I Paint My Wall or Ceiling Speakers?
Yes. Manufacturers understand that the whole point of flush-mount speakers is to conceal their presence. In wall speakers are designed to be painted with the same wall-paint you use to decorate your room.
