I have a bunch of 12 and 14 awg thhn or thwn lying around because I do electrical work and I am wondering if I can just use that from my amp to speakers because it will only be going 2 or 3 feet and I don't want to have to buy a 25 or 50 feet roll of 12 awg speaker wire. Also am is a 150 amp fuse enough for this 500w rms amp or should I get a 250 amp fuse?

Would it matter if I used a 250 amp fuse since it is only if something shorts out and I might plan on adding a second amp and running 1/0 to a splitter by both of them.

You fuse for the current capability of the wire. 150 is the most I would go with 4ga. Fuses are cheap if you upgrade your wiring sitch.
I thought you fuse for the total sum of the current draw? Like in the manuals it says what fuse size to use by the battery. Why would I fuse for 150 amps if my amps draw around 100 amps?
