Feel free to ask any questions to do with running wire or what AWG to use. If I can't answer it, I will get the answer for you from elsewhere. Thank you.

Keep in mind that length is a factor here as well. If you're doing a long run (>20 feet), you should use one size larger. It doesn't hurt to use a wire size that's larger than necessary, but it will usually cost more and can be more difficult to install.

Power Wire:

10 gauge: ~35 amperes
Class D (~70% efficiency) - <350 watts
Class A/B (~50% efficiency) - <250 watts

8 gauge: ~55 amperes
Class D (~70% efficiency) - <550 watts
Class A/B (~50% efficiency) - <400 watts

6 gauge: ~87 amperes
Class D (~70% efficiency) - <875 watts
Class A/B (~50% efficiency) - <625 watts

4 gauge: ~140 amperes
Class D (~70% efficiency) - <1400 watts
Class A/B (~50% efficiency) - <1000 watts

2 gauge: ~220 amperes

Class D (~70% efficiency) - <2200 watts
Class A/B (~50% efficiency) - <1500 watts

1/0 gauge: ~350 amperes
Class D (~70% efficiency) - <3500 watts
Class A/B (~50% efficiency) - <2500 watts

2/0 gauge: ~440 amperes
Class D (~70% efficiency) - <4400 watts
Class A/B (~50% efficiency) - <3000 watts

4/0 gauge: ~700 amperes
Class D (~70% efficiency) - <7000 watts
Class A/B (~50% efficiency) - <5000 watts

Speaker wire:

22 gauge: ~2.2 amperes
8 ohms - <36 watts
6 ohms - <27 watts
4 ohms - <18 watts
3 ohms - <13.5 watts
2 ohms - <9 watts
1 ohm - <4.5 watts
