12 ga.
Bathrooms and kitchens are wired with 12ga per NEC code.

A 14-gauge wire will be fine. Even at full rated power, you'd only have about 10 amperes of current running through the speaker wire; most of the time it will be much less. There won't be a significant voltage drop over a 5-foot wire run. I'm not sure what you're asking with the 600 amp / 400 amp question. The power produced by the amplifier will be divided evenly between the two subs.

wow i cant get over how many wrong answers people throw around here like they have any idea of what they are talking about. that would be like me( electrician ) giving someone advice on doing their taxes. I blame the stupid point system that they have here. But anyway lets get to your question.
The first thing you need to figure out is what is the wattage or amperage rating of the unit itself and you should find this somewhere on the unit it self. If this is a standard nu tone or similar brand unit than i am willing to bet that the heater is rated for 1200 watts and the fan and light are maybe 200 watts max, together giving you a total of maybe 1400 watts. And the maximum allowable watts on a 14 gauge wire or 15 amp circut is 1440. (yes, all you know it alls 1440, I know some of you are screaming 1800 watts but as per the NEC you must never load a residential branch circut more than 80 percent.) with that being said and given the fact that i dont know the exact wattage of your unit you would be better off using 12 gauge wire and dedicating this just for the unit. meaning it should be a home run from the panel. with 12 gauge wire you are allowed a max of 1920 watts and i would be shocked if your unit used more than that. I know what your thinking right now, damn i need a home run i dont want to do all that i just want to tap off something thats close and make it easy, but i can almost garanuntee you will have a problem later on or you will be creating a bad situation if you have the heater/fan/ light on all at once and there are other things on the circut. Sure go ahead take a chance, and your chances of creating a fire hazzard just went up. How do you thinkd most fires start in homes? And contrary to what someone stated all bathrooms do not need to be wire in 12 gauge. only the gfci has to be. There are more rules to this but IM me if you are interested in knowing. Trust me I am all for the gung ho home owner but when it comes to electrcity just make sure you have a good idea of what your getting into before you start. I have personally seem alot of crappy half *** wiring that people do to their homes and when they call me to fix their problems sometimes i dont even want to get involved because i dont want the resposibility god knows what else they did and if something went wrong i would be the one to blame. any way good luck and be safe
PS i dont think i have ever seen a bath fan/heater rated for 30 amps(10 gauge wire ) in my whole time as an electrician. Please be carefull of what advice you take from this site

It depends on how many total amps it is with everything running. if it is 12 amps or less, use a 14 ga wire on a 15 amp breaker. If it is 13 to 16 amps use a 12 ga wire and 20 amp breaker. And if it is 16 to 24 amps, use a 10 ga wire with a 30 amp breaker. Adjust your wire size larger for a voltage drop caused by a long run of wire. The unit is not required to be connected to a GFCI. Take electrical advise from untrained people at your own risk.
Edit:
Ha ha, I must have hit a sore spot about the untrained people and got three thumbs down for a correct answer. Tony nailed it to explain my listed amperage. His answer is correct. You must limit your continuous load to 80 percent of the wires ampacity. Thus my answer. These things weed out the qualified from the unqualified. All you armchair electricians do is keep the firefighters busy. And an occasional coroner. But hey, houses are cheap right?

12 or 14

Use 12 gauge as they are rated for 20 amps, 14 gauge is rated for 15 amps.

OK people, this is obviously a multiple choice question. Either 10 gauge or 14 gauge. Not 12, not NEC code or other nonsense. 10 or 14, simple. Right? From only the two choices given, absolutely 10 gauge.

Before install any appliance first check out UL in label , then see amperage of fixture .
Cause of vaporization in bath you must take power from one GFCI receptacle and cause of heater /fan you must have over 10Amp loading and wire gage Min 12/3 and safe 10/3 is recommend .

If there is a heater in it then I would suggest 14 gauge as the resistance is much higher with a heater. Have a great day.

12 gauge with a g.f.ci. on a seperate breaker by itself!

12, and it has to be on its own designated circuit breaker. I put them on a 20 amp G.F.C.I. Read the instillation instructions that came with the fixture.
