is it true...

that a class d amp will over heat the voice coil in a sub 2-3 times faster than a amp in a diffrent class?

No...I don't see why it would.

Um not true.....why would someone make an amp that could damage a sub that way

The older ones did. Back when class D was fairly new as far as mass production went, the switching speed was not nearly as fast as it is now. As a result, there were random bits of DC voltage in the output, especially if using a higher crossover point.

Dont think so but someone might think that the class d is not as clean as a class a and think that the voice coil would get really hot since its not as clean. Just looking at it in someone else POV.

Not with todays technology. I have yet to blow one piece of equipment yet.

Class D is not made for subs. It just so happened to work better when first introduced due to the aforementioned switching speeds. As has already been stated, with the advances in technology and the higher switching speeds, it can now be successfully used as full range.

No, that's false

And yes, you can have a full range class D. Infact, there are many available for car audio. Even moreso for home audio.

Now, not all class D amps can be ran full range. We're not advocating you toss your Hifonics Brutus on your component set. But the class D amplifiers that can not operate well full range can't do so because they are design limited. It's not a limitation of the technology, however.
