If you had to choose one of these two amps to run at 2 ohms these are the 2 I am picking out of. Im not just looking at whatever one puts out the the highest watts what would be better on sound quality and be a better quality build etc...
If 800w+ @2ohms is enough power, and you don't plan on using the 1500w of 1ohm power that the BX1500d can provide the definately go for the MTX. Better made amp, more reliable.
Well, they are both class D amps....so there is more distortion than a A/B amp. I would say that MTX has better SQ but not so that you'll notice.
Look at the THD of each amp...My 801D was tested @ .421% Most class D amps just guarantee less than 1%. I've never used them side by side so I can't tell you for sure.
class a b D doesnt matter unless your going to a compotion... the normal ear can never notice... thats a bunch of bull in my opinion, i kno alot about electronics, not just amps, cell phones computers, take any amp apart, and you will see inside they all use basicaly the same parts, its all quality in constroction............class my A$$! you cant tell the difference unless its hooked up to a machine!
I bought a remanufactured 801d over 2years ago and thing has been flawless ever since, its built solid and lasts along time. Dont know about the Hifonics amp though.
