Sounds like a short.
I don't ever use spades becasue they can short when twisted.

Why did my amp just crash and burn ?
I just installed a new set of AQ Robin Hood Zero cables. A little hiss sound from the speakers prompted me to adjust the spade connecters just a little on the amp. Then low and behold , the amp just cuts off and currently appears dead as a doornail.
What just happened and needless to say this is an absolute bummer.
