I do plan to go bigger so I guess the real question is Can you have too big of wire?

no. power wire can never be too big. unless its too big to fit under the carpet or panels, etc.

Okay, another question, my dad said he's got some copper wire I can use is that fine to use for speakers, ground, and battery? I'll be putting a fuse on the one for the batt.

if it's single strand copper wire, like electritions use, negative... also use the same gage grounds as your power runs... i.e. if you have 1/0 to a amp, use 1/0 ground... and if it was me get some 1/0 and run that...

this is the site everyone recommends... i use welding wire meself...
