I would just grab a spool of 16 and cut all new pieces to length, don't try to length old pieces.

Subwoofers don't put out power amplifiers do so the better question would be "how much power are you giving the subwoofer?"
I'd say 12-14ga should be more than adequate for the subwoofer and 14-16ga for the speakers.

and don't mind Cadillac he's a complete noob/tool.

amplifers put power to the subwoofer which the subwoofer turns into a different form of energy. this is the chain of events that happens with speakers. we measure this ability in wattage terms because its electrical based.

chances are it all runs off one big amplifier so knowing the amplifiers specs without knowing the subwoofer specs doesn't help with choosing wire just for the subwoofer now does it?

Don't try to defend yourself and look smart it was a stupid ass statement and any audio enthusiast would have shit on your for it, I was being nice if anything by how I said it.

unlike you i know how stuff works and don't mouth of ignorance. once you are on my level instead of playing connect the dots you see everything as the whole picture and get straight to the point.

What's your level? stock car audio? ok I'm glad I'm not on your level bud, your level is walmart and best buy.

my parents have a home system, and you have to plug the subwoofer into the wall... so i think it runs off its own power.

Not all home theaters come with a powered sub, some run off just the amp. The higher end ones come with a powered sub tho.
