The insanity continues!
At lunch I grabbed a DMM and did some additional testing. Found that my voltage never goes below 14v at the amp with the vehicle running. I still can get the amp to go into protect without any speakers connected.
I called Kicker back (great guys by the way) and they said maybe its OVER VOLTAGE. Apparently the specs indicate operating voltage of 9-16 but may run into problems at 15.2 or so. This would be consistant when what I was seeing with the DMM, large draw, then the voltage "spikes" up to 15.1 or maybe a touch more. Kicker is checking to see if this is a known issue with other ZXs. I will keep everyone updated with the info.
