parasitic drain test + Speaker feedback

Ok,
my batter will drain over the course of a week if i don't unscrew the negative battery terminal kill screw.

Aftermarket radio and alarm so i know i have a lot of potential for issues.
Since i bought the car 5 months or so ago, I have always had a speaker whine that matched the rams. its gotten worse and i need to fix the issues.

on to the parasitic drain test which = .334A Negative terminal to disconnected negative wire.

no when i did this test i got feedback from my speakers, popping.crackling.

i did not expect that, but will be looking into the speaker/radio system and their grounds.


I am working on this today but figured i should post incase others could help pinpoint the issue. thanks in advance.

I'm wondering if your radio is wired correctly, it may not be turning off when the ignition is off. Check to see if you have a condensor (filter capacitor) on your voltage regulator.
