any ideas?

Do they drain there caps on a cycle or anyhing?

no

yes only if there's an internal short in the amps. The best way to test this is to check the amperage going from your battery to the amps when the amps are off. If there's a fairly large amount of amps (like 5 amps would be a large amount if they're off), then there's an internal short somewhere in one of the amps.

To be honest .5 amps would be a fairly large amount if they are off. On a modern car the acceptable battery drain is .05 amps. I would be ok with up to .1 amps, but anything more than that is going to drain the battery after a couple of days of sitting. A drain as big as 5 amps will drain it overnight.

An amplifier with B+/B- connected and no voltage on the Remote will still draw a tiny bit of current to power the muting circuit, but not enough to drain the battery.

So when the car is started, is the alternator providing the power for the amps to use or does the battery still have some input?

when the car motor is running, the battery should be being charged by the alternator, so it doesn't matter.

Everything runs off the alternator, until you exceed it's available current. Let's say your alt is rated 60 amps at idle, and you are swinging 100 amps through your amplifiers. In this case, it will begin to draw from your battery, which is why we see a voltage drop and often get headlight flashing

If your amp is bolted/srewed straight to the chassis, some will actually stay on - even if the stereo is off.

anyone pics ?????????? but no, yes your right tom!!!
