If you probe isn't set to 10x, set it to 10x and try again.
If I set the scope to 10v/d and 50us this is what I get at max volume. Is this a clipped signal? Both channels perform identical no matter the setting.........Thoughts???

Yes. Set the timebase to show 3-4 complete cycles. Try adjusting the trigger level to get it to trigger properly. Unless you're using two probes/inputs, it should only have one waveform.
Whenever using the scope, unless you have a good reason to do otherwise, adjust the timebase to display 3-4 complete cycles. Set the vertical amp so that the waveform is deflected between 2 major divisions and 4 major divisions (the top of the graticule).
If both channels perform the same with a load, it's not likely a driver issue.
Are you sure that you don't have an intermittent connection on any of the components between from the drivers to the gates of the output transistors?

Ok Perry think I have what you want.
Scope settings:
20 vol/div
1 ms
100hz test tone
first pic is 1/2 volume 15
second pic is 3/4 volume 25
Is this the clip signal you wanted to see?
Both channels perform identically.

Wondering where I should go next? Its like the squaling stays for a few seconds, draws some current then you hear a pulse like the amp is turning on and it goes away. It makes the same sound when you disconnect the remote wire but only for a second. Almost like a screech. Only the one channel does it though. I must me getting some serious feedback for a few seconds somehow, just not sure. Maybe the IN4003's ? Is there a way to check the rca ground shield other than a wiggle test?
