Alright, I'll look into 0GA all around, can I run to Lowes and get 0GA? Or is the wire at the Car audio shops special in some way? Because the only car audio shop in my town they want 3 bucks a foot for 4ga! it's like $5.50 for 0ga, GEESH!
Edit: someone said to upgrade my speaker wire as well, I think it's like... 16ga? Way little, what size should speaker wire be running at?
