What's gauge do I need for 400 watt car speakers null

400W RMS or 400W Peak? 400W RMS would be more for a subwoofer and you should run 12AWG wire for those. 400W Peak which will be about 100-150W RMS (continuous and what really matters, peak is an advertising gimmick and means absolutely nothing), you’ll be perfectly fine with 16AWG copper wire. Make SURE you are getting COPPER wire because there is a PLETHORA of cheap CCA (Copper Clad Aluminum) wire on the market today and there are no disclaimers or warnings on the packages. CCA can only flow about 20% of what copper can for the same gauge! Also be careful of the terminology “AWG” and “Gauge” or “Ga”. AWG is what you want. Gauge/Ga is a junk Chinese standard. This wire is AWG even though the packaging states “Gauge” but that’s because quality companies haven’t caught up with the fact that cheap companies are cheating with sub-par standards!

16 gauge should be fine but I always opt for more. I usually go with 12 or 14 gauge to be safe and diminish signal loss.

This speaker wire is 16 gauge, it should work with your car speakers.
