You want to mount it in an area where ventilation can flow, that way it keeps your amp cool. I'm guessing your amp is overheating. Do you ever notice it going out maybe 30mins - 1hr of bumping ur subs, then shuts down?
About adjusting your settings, look in the manual. They'll tell you specifically what settings it should set. All amps are diff, so you have to adjust accordingly.
Regarding the fuses, you should have a fuse(s) within the amp and also one nomore than 12" from the battery terminal. The amps of the fuse near the battery is determined by how many watts your amp is. The power cable is also the same. I mean it doesn't hurt if you're using a lower rating fuse, it just means you'll be replacing that fuse more often than normal. By all means, don't use a higher rating, cuz your might just fry everything. Look on the kit that was supplied and match correctly. Good Luck!
the fuse near the battery should be rated below the maximum amperage your wire is capable of carrying, to prevent a short causing a fire/melting all the wire.
it has nothing to do with the amperage of the amp directly, though obviously you need to have an equal or higher amp fuse (as well as the wiring to back it up) at the battery that is sufficient to cover your amp's power requirements.
