[DML] tracking down a power drain

Hi Group,
I'm trying to determine why my battery is too drained to start the car  
after 5 to 6 days of sitting.  By inserting a digital multimeter in-line  with 
my battery, I determined that my Lockzilla draws about .01 A while sitting  
(drops to zero when Lockzilla is disconnected).  In addition, I have a  
stereo system with an amplifier.  The amplifier, when isolated, seems to be  
drawing about .03 - .04 A with the key out of the ignition.  The draw is  
constant even when I remove the remote and speaker leads from it.  The amp  is 
not on as per the LED's on it, but it is definitely pulling some power.   When 
I disconnect this amp and the Lockzilla, my DMM fluctuates between 0.00 and 
 0.01A (I can't find that last half-amp by pulling fuses, maybe the meter 
is a  little off) and when both are plugged back in it reads about 0.05 A.   
Is this enough juice to drain a battery in less than a week?  I have not  
put a meter on the battery to read the voltage after it sits for a week so I  
don't know how low it's getting, but certainly low enough to not turn  over.
I know it's not exactly DeLorean related, but the amp is a JL Audio 250/1  
monoblock amp for a subwoofer.  The instructions don't give a resting draw,  
so I'm wondering if that is typical?  Seems a little high, so aside from an 
 internal problem with the amp, what else could go wrong with it?
