hey all, since it startd to rain heavily, few months ago my car alarms noise has startd to sound retarded, e.g the unlocking noise sounds very diff n wen i intentionaly set the alarm off the noise sounds high pitched and ocasionaly goes on n off and makes weird noises even tho the car alarm is still activated, the speaker part of my alarm is clearly ruined and my question is can it be replaced or do i need to purchase new alarm system? central locking and all that still works and its a Brant 3 Point Immobilser alarm system. hope some1 can help. thanks in advance.
