Anyone have those M2200s floating around? How hot do they get?
I've been scared off by the amp manuals suggesting you have a separate 15A circuit for them, yadda yadda, tons of clearance, yadda yadda, since I don't have much of either.
If you crank them with music at 90-100 db average, yep, they'll get hot after about 20 min. I've kept them going alot longer than that (when 1st testing them) without shutdown. Of course, if you can stand music for that long at those levels, you're a better man than I.
Mine are stacked on top of each other with about 3" clearance above. No need for separate circuits.
