Battery keeps discharging. Mechanic says he thinks it is the amplifier in the trunk. This is also part of the computer system? Can anyone advise fix

The amp is not part of the computer system. I would first load test the battery to make sure its healthy and have the alternator tested as well to make sure its opearting at peak effeciency.
If you suspect the Amp...unplug it and see.
FYI...the cars battery may be junk.
