batt dying when car is off

yeah the only thing i think would do it is the head unit but i dont know. we installed it withough a harness. just whitecapped the balls out of it. theres nothing else on. i took the power wire off of my batt from my amp and its still doing it. i took the head unit outish and when i jiggled the wires, the speakers made the popping noise. is that supposed to happen?

yea have the alt checked out first, easiest thing since autozone does it for free. that happened on my last car and ended up getting a new alt.

yeah i had it checked and they said that the voltage was fine but the batt was too low to read.

how is that? its still charging the batt. the batts just dying for some reason.

The diodes in the alternator could be bad that would allow current to flow backwards through the alternator system which would drain your battery VERY quickly best thing to do is to test the diodes in the alternator im not sure if autozone or any of those places will do that but you can check
