I saw another post regarding going from stock 136 to 180 amp, and the wiring is barely good enough for that.

I want to move into a 240 or 320-amp alternator.

My question is, do I need to upgrade the wiring beforehand?

Nothing is drawing more power than usual, but my current stock alternator is dying, and I want to future-proof it in case I get a sound system.

If I don't, I will replace it if I need wiring.

Yeah, I'm taking it to a shop.

Thanks
