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. It’s cost-effective and easy to work with.

Ask your advisor to recommend the proper gauge for your installation.

How much wire do you need?
To figure out how much speaker wire you need, run a string from your receiver or amplifier location to each of the speaker locations. Measure the string, and then add a few extra feet (to provide some slack for easier connection to your gear). Then add a few more feet, just to give yourself a margin of error.

What type of wire do you need?
You can buy speaker wire with connectors or without. If you buy wire that doesn’t come with connectors, we strongly urge you to buy banana connectors for at least one end of each wire. Attaching bare wire ends to a home theater receiver is a real pain.
