Angry 2003 Deville Radio install - Help needed!

I have a 2003 Deville without the Bose package. I've exhausted all of the research available to me. My factory harness does not seem to match what I've found online. I'm installing a Pioneer AVH-X2800BS. The wiring harness from the car has the following color wires and pin location. Top 1.O 3.LY 5.Black 6.Purple 11.Clear tube 12. Purple/W 13. Blue/W 14.G 15.G/Black. The bottom: 4.R 5.Y 6.Purple 12.Tan 13.G 14.Clear tube 15.Clear Tube 16.Black/W. I understand from using a multimeter that the Top 1.O = constant 12v, Top 5.Black = Ground and that is all that is clear. The two purples Top 6 and Bottom 6 are constantly bouncing around the meter when ACC is on. I'm assuming the Top 12,13,14,15 and Bottom 12,13 are speaker wire because of the 3.98volts when in ACC. That's only 3 speakers. Any help would be greatly appreciated.

My question is I don’t know if the radio is bad or the amplifier is bad.... I am highly consider replacing the headunit with a single DIN unit with bluetooth. What kind of accessories should I look to buy to create a complete headunit stereo install. I dont really care if the steering wheel buttons dont work or the On-Star service doesnt work but I do have the XM satellite service on the car, is there any way to keep the factory XM antenna and setup into a new headunit?

The radio system is complex. IDK that there's an aftermarket radio that will be compatible with car. Radio can set codes and is diagnosed with Tech2.
The vim and vcm ( onstar) for satellite antenna.
