ive got a short... room fuse. and what fuse are the speakers on?
 

so i have 2 shorts i think. the main one is on the room ruse, dont know about the other. if a speaker had the pos and neg wires touching, would it make sound or anything noticable to indicate that?

If a speaker had the two wires shorted together, it could crackle or blow out the amp or headunit output (depending on what was wired at the other end).
