Only 10K I have broke was a 27" shaft one I had on the roof of the Suburban, and got snatched off by a low hanging power line that had fell across my road after a storm and was about 6' off the ground when I drove under it one night...
Yep mine broke there also but it is it's weakest point by still strong as any in the business and only happens when severely abused.
Kale has a great product but I will not be drawn into any false claims of audio gain.
