Capacitors wires question

[Russ130]

I going to install a 3000 watt peak power system in my car. I want to add a capacitor in it as well. What gauge wire should I use? I know if I was not running a capacitor I should used 0 gauge. Should I still use 0 gauge or can I use smaller gauge?

Capacitors are usless unless you're using banks that have ~200f+. Sounds like you're using one of those cheap 1-3f caps. Useless, don't use it.

I haven’t installed anything yet. I was just asking what gauge wire can use if I do use a capacitor.

Guess it depends on the capacitor

What’s a good inexpensive one that you recommend?

I doubt you're actually putting "3000w peak" in if you're talking about a cheap capacitor. Ditch the cap and just get 4 gauge ofc. That's all you need.

Ok thanks

Quit looking at peak power. My guess is your gonna run 1/2 that which most of the time is RMS power, root mean squared, continuous power.

And ditch the cap. It's just a band aid cheap route to beef up your electrical. You want to at least do the big 3. Plenty of YouTube vids/know how.
