For most systems 16 gauge should be more than adequate. Only with extremes of distance ( something like 50 + Feet ) or very high current / power needs would you have to use a larger wire size.
I use 12 gauge, but I'm one of those who believe in Over Engineering.

Hi everyone I was wondering is 16 gauge speaker wire OK to use.
the cheaper brands of wire like RCA are copper clad aluminum which is fine for shorter runs but if you have a bit longer runs or are using tube gear i would make sure its pure copper as aluminum has a higher resistance than copper.
100% depends on what you are connecting it to
16 awg wire will handle 13 amps at 120 volts. The likes your amp will never produce.
Sure. You can always compare 16 gauge to 13 gauge simply by doubling up on the wire.
Depends on the impedance of your speakers and the damping factor of your amp. The idea from some quarters is to keep the ratio at least 25 to 1. So if your speakers are 4 ohm then the total resistance of the wire including the source impedance of the amp should total less than .16 ohms. 1000 ft of single strand of 16 gauge wire resistance is 4 ohms. But as we use two conductors that would be 4 ohms for 500 ft, There fore .16 ohms would equal 20 ft. as the maximum recommended distance. The current handling capability is a totally different story. remember 16 awg lamp cord is carry constant current where sound current varies tremendously. We know 16 awg can handle. 150 watt bulb with no issues. Thats a little over 1.2 amp. with 120 volts. So I see no problem using a 80 watt amplifier. Even though the current will be higher, the voltage will be much lower.
Hey thank you for the link that is extremely helpful thank youIt's fine for runs of up to about 50 feet. Longer than that, you may want to go a bit larger.
