Hi all,
After not driving for a few days, I've just come back to a flat battery. This never used to happen before installing a stereo amplifier, although of course it could be a coincidence. The amp spends most of its life in a standby mode, as there is a cable from the head unit which switches it on when the HU is switched on.
Is it normal for an amp to drain a battery, even when it's switched off? I am willing to believe that the battery wasn't in the best nick, but still... What sort of current should the amp be drawing in standby mode? I wonder if the amp is faulty.
