I had 12v at the stereo on the ignition feed but only 0.75v on the continuous feed and no power was getting to the amp. All fuses were fine.
All sorted now.

I had to unbolt the seat up front, and slide it out of it's rails in the back....after unbolting the rear section of center console, and anything else to loosen the carpet all around the seat and console area. Have picture of the corroded splice....doesn't look like water caused this.
