Judging from what I read on both the manual and the unit, the internal power amp only supports 8 and 16 ohm boxes. What happens (or can happen) if I use a 4 ohm load instead?
Speaker load on a powered KPA

As long as you don't turn it up too loud, it *should* work fine. In most cases you'll hear the speakers starting to distort well before any actual damage happens, and that's going to be at a pretty high volume anyway. Start with the output at 0, then slowly turn it up.

The power amp has a built in protection circuit that prevents it from overheating... but besides that: before the amp overheats you'll most likely be deaf
Somewhere Kemper also wrote that it is ok to use a 4 ohm cab if you don't turn the volume up to maximum.

The current through the FETs (or transistors) will be a bit bigger then with 8 or 16 ohm. Therefore you have less power before the safety will trigger.
Compare it to PA amps, loaded with 2 ohm loads.
