Battery discharging

If i don't turn my car on everyday my battery will die i don't know why but i think there's a short circuit, because there are some sound system wires loose in the trunk ( the car came like that) anyway i think that's whats causing the battery die but i took out the fuse that was powering those wires so now i don't know whats the problem.

Could be one of several problems.
First have the charging system tested and the battery load tested.
Will the battery go down in a couple of days if it is disconnected?
If so bad battery.
If it stays up disconnected and goes down hooked up.
You need to have a amp/volts draw test run on the electrical system.
