OK, here is the latest - the processor is a Kicker Front Row and amps are JL. After driving for 2 hours, the whine begins to come in getting louder for about the next 15 minutes. I can kill the sub amp with a switch so I eliminated that easily. Head unit on or off, no difference. I can lay my hand on both amps and they are about the same temperature and not too hot to keep your hand on - I will check temp on them today to see how hot they get. Since it sounds perfect during that first 2 hours, I doubt it is the grounds, but will double check. I suspect the processor is mounted under the console and from what I can see on line looking at the manual, it probably has no fan. I think heat is the enemy here on that processor. I'll try to find it's location and do some more checking. Thanks for all the help!!!!
