In-Wall & In-Ceiling Speaker Wiring

If you're attempting to install in-wall or in-ceiling speakers yourself, here are a few things to keep in mind about speaker wire.

1. You will need a special wire to run inside walls that complies with your local building code. Usually UL rated wire labeled CL2 or CL3.
2. Speaker wire gauge will differ depending on how far your running from your receiver or amp. Less than 75 feet 16 gauge, 75 to 175 14 gauge, more than 175 feet consider 12 gauge.
