ground should be 2 feet per ground and no you dont need to be fused for grounds.

2 feet of ground each time

got 2 amps... you can have 4 feet

have 16 amps you can have 32 ft of ground

1 more question. would anything happen if say i powered a 500w amp using a 1/0 gauge kit?

other than having a hard time fitting that wire into the amp... no

no problem at all

you wanna get that negative charge out of there as quick as possible and the longer the wire the more resistence there is too keep that negativity in there... or something like that.

whether your wires are 2ft or 8ft really isn't going to make much difference. The object is to keep it as short as reasonably possible. Chances are it's not going to effect anything, and almost certainly not to an audible degree, but it doesn't make a lot of sense to have 3 or 4 extra feet of wire in the current path if you don't need it.
