Is there any reason to add a wire from the post on the ALT directly to the battery?

I ended up adding an 8awg directly to the battery as I have a lot of high draw items ( three fans, 100w stereo amp, subwoofer) so my ignition switch was getting hot because everything was running through that wire, but if you don't have much I would think it would be alright.
