Amps running hot, for no apparent reason.

So, I was working on my truck, speakers playing at a very low volume, but the amps get hot even at the very low volume. What could be causing this, it makes no sense to me. It is about 95 out here today, but they never get warm and it seems like just powering them on makes them hot.

Sure they are wired to the right ohm load?

go throw them in the river. that'll cool them off.

grounds? wrong impedance?

Nope, it's all 3 of them. I know what I'm doing fellas. They stay the same temp whether full throttle or low volume.

2 9.1's, 1 ohm each, not strapped.

9.2x, 6.5 component set, ~4 ohms.

Shouldn't be getting very warm. The 9.2x gets hot hot.

my amps get seriously hot when it's 95 out...where they sitting in the sun or did you notice that they were cold, and turning them on got them to heat up

I was in the shade. The amps shouldn't have been how warm/hot they were just by turning on.

It is somewhat, just I don't feel like messing with it. Everything is set up correctly, I know that for a fact. With the car off, the amps see 12.7v.

Buck my 9.2 got hot as an oven. I mean it would actually burn your hand if you touched it after a few mins of playing. It had ample airspace so that was not the issue. But no matter how hot it got it never went into protect so I guess the heat sink was doing its job. But I mean it got hot hot like toss some aluminum foil and cook some burgers hot.
