Every amp I put under my seat got hot enough to fry an egg when I pushed it. Even low volume the others (class A/B) would get hot.

This is my first class D for my mids & highs. This amp gets warm normal playing and I managed to get it hot when pushed to extreme. There was a difference of less heat, but for class D I was hoping for cooler.

Now for the sound:
I had four other amps for my front in the past and they all had slightly different sound signature. This one is no different. I would say the low level resolution is slightly exaggerated, while also somewhat of a boost or extension past the upper highs. This creates a sound that, to me is best described as very "high polished" and "shiny." The only drawback is the depth of field is not as deep as I have heard elsewhere, but the sense of "shiny, polished" clarity is impressive nonetheless.

Also, it does not have either the sweet "MOSFET" sound, nor does it have the dry "bipolar transistor" sound. Its sound is unique and of its own, and never harsh when driven hard, just a lil' "glassy" at max volumes. This lil amp blew FOUR OF MY INFINITY SPEAKERS! Both tweeters first, then woofers, as they were all 2-way 5x7 speakers, and they were only pushing the kids/highs. The amp would shut volume down into protection just "after" it burned them!

I was going to upgrade to the "Kappa Four" amp to see if I liked the sound, as I prefer a sweeter "MOSFET" sound than this, but I found a better speaker match than the Infinity, which are too brittle sounding in details and blew out. With my new speakers, the sound is more natural in upper mids to highs, and just right without blowing out like the Infinitys and almost half the price! They are the "Precision Power PPI PC.572" 5x7 2-ways at 3 ohms. Also with external crossovers just like my Infinity Kappa I blew! So, I will keep this setup until something dies!
