Mono amps have 2 sets of + and - right. Whats the point of that? My friend has a car that they bought from some guy that worked at BB and it has all Xplod stuff in it, and it has a mono Sony amp and has 2 subs in it, 1 wired to each set of + and -. Is that going to ruin the amp?

1. Not all monoblock amps have that.

2. If it does, it doesn't matter what set of terminals you use.

but is it bad to have 2 subs hooked up like 1 to 1 set of + and - and the other sub to the other + and -?

the two pairs of terminals on mono amps are schematically the same connection. They are parallel to each other meaning if you connect a 4 ohm sub to each connection the amp sees 2 ohms.

If you opened up the amp it would look something like this:
