I wouldn't say stupid, just a different way of getting to the same end result.
Plus, I need an amp that'll give me 600 or so watts @ 4ohms...find me a class D amp with similar build quality and durability as my 2.2HV, and you're going to be spending quite a bit more than what I paid for my first 2.2HV.
I also believe that my 2.2HV is more flexible than a class D mono amp. What If I change subs and I need full power @ 8ohms? Yep, it'll do MORE power @ 8ohms bridged, or if I decide I don't want to run a sub any more, it'll power comps too, 2x185@ 4ohms is quite a bit of power for comps.
Not saying class D mono blocks are bad, but they don't fit my needs, I haven't used one to power a sub in ohhh I dunno, probably 5 years now //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
