I bought a Hifonics amp from and ran it at 1 ohm all day long and it lasted for over a year. It was a Nemesis NX750d. I bought a BX1500d from ikesound and it blew up within a week. Ever since then I switched to an Orion 1200d and couldn't be happier //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif
Side note: I know of 2 people running Hifonics and both are having good luck. One is running a 1000d and has been for 2 years or so, and another has a 1605 and after RMA'ing a DOA, his has run fine for a couple months now.
