[QUOTE="Jcsaudio, post: 8649673, member: 673752"] He is right about the amperage of the alternator in/out of the battery, but that doesn’t matter. You should try that voltage drop test on all your suspect connections like the fuse block. Battery connections, and ground connections (at battery). Through the process of elimination, you can narrow it down to the cause, assuming you have a bad one somewhere near that amplifier. That 1 volt difference you stated at the amplifier doesn’t just disappear on its way to the amplifier unless there is enough resistance to make that happen. If there is a bad connection somewhere, then the voltage will drop at that point when high current flows through it. For example a voltage drop test across a 300 amp starter circuit on each side of the positive cable should be less than .5 volts. [/QUOTE]
