Fusion Amps getting HOT

[Miller92063]

Anyone else running into this issue?
Im running a 8 channel, only using 6, and a 5 channel with bridged speakers and a sub. The amps are getting so hot I cant keep my hand on them for more than a few seconds. New wiring was ran for all speaker wires so I should have any ground issues.
I did notice a slight ring in one of my tower speakers after the install the other day and need to run that issue down, but dont think its relevant to this issue since its happening to both my amps.
TIA

It could be just the design on the amp, does it have a heatsink?

My kickers do not have a heat sink, the entire thing acts as one and you cannot touch them. I've had them going full blast for hours with no issues though.

I ran them about 6hrs yesterday to test them and they did fine. Did notice a hum from 2 speakers so I need to track that down now though.
