Here's the update- with key in accessory position, multimeter reads .63 V DC and 0.00 V AC on speaker terminals. With engine started, multimeter reads .52 V DC and 0.00 V AC on speaker terminals. I think we have our answer- my amp is putting out DC current, just like you guys were thinking...

I will be sure to try that tomorrow after work and I will report back! I did hook up the multimeter to the speaker outputs earlier today and it fluctated between about 2.15-2.4 V, but I can't remember if it was AC or DC... I greatly appreciate the help. And that stinks man! Another reason why I...
