For how many watts is this kit good for ?

The wiring is good for over 1000W, but the fuse is only 80amp and the fuse holder is the weak link because it is an 8 gauge fuse holder. You need the proper fuse and fuse diameter for true 4 gauge performance.

Will this work on a 2000 watt amp?

Only if you get a stronger fuse and proper fuse holder. The one I got was only 8 gauge for 4 gauge wiring? Fuse is only 80 amp. Might have been a mistake, but attempting to contact the seller to get the proper fuse holder.

I am going to be running four speakers 2 in front and 2 in back. Would i need an extra rca cable for my amp?

Depends... If you want them to be on a separate chanel yes.
