Here's a handy little calculator I found online a while back... That's a direct link for you, but here are some more links to keep available for good reference!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

thanks for that link, totally awsome.

I was just looking around and found one of those inline fuse holders that alot of people have next to their battery. I have a distribution block in the back that accepts ANL fuses but they dont go as low as 20amps which is what i need. Is it ok to put in the 30amp fuse inline after the 60. Because the 30 would blow and cut off the circuit right??

Yep. But keep in mind that you're fusing the wires, not the amp. The amp has it's own fuse. Use the fuse that's appropriate for the wire size. You can use smaller, but it's not necessary or appropriate to match the fuse ratings of the amp when you're fusing the wire.
