is it my alt?

about 3 days ago now i noticed a hum/whinning noise from my subs wich was never there before. i do have a capacitor with a digital read volt meter on it inwich would always read 14.8 volts. when the car is at about 2k rpm the whinning stops. so i decided to check my cap for voltage and it is now reading 13.20. the battery under the hood is brand new the one in the trunk is about 6 months old. the alt however is the original stock alt at 104000 miles on it.
