Just to provide you guys with an update:

I received and installed the TOP Hi-FI Lear L6 amplifier. It worked fine and it is a "plug and play" deal, no programming required.

The audio system is working perfectly now!

The only issue I had when installing the amp was the brace system to unplug the wiring harness. The "brace" needs to be pushed all the way to left to the wiring harness to unplug. Other than that, piece of cake!!!
