8 gauge is good to supply your amp with 60 amps. 4 gauge is good for 120 amps.

Check the size of the fuse your amp uses and reccomends, and make the choice based of this. For example, if it's a 25 amp fuse, 8 gauge will do you fine.

If you plan on expanding your system in a few months, such as adding another amp, run 4 gauge. You can split it later without much effort. Unless you are running a HUGE system, 4 gauge will generally do you fine.

It doesn't matter how much RMS you're amp pushes.... What matters is how much ampage your amp pulls...
