I'm in the same boat, I need the same power/load and have a planet audio 2250, but not about to run it at .5. I've seen people run them at .7, but I'm not going to let the smoke out trying to go lower. If you wanna do the testing its up for sale...hahalooking for any amp that does 2k rms at 2 or .5 ohms for no more than 325 shipped. if i was 100% sure planet audio are .5 stable id buy one of those.
i think the sale is factory direct. im going to be getting a pair of the SAZ 1500D's and one of the 100.2's //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifwhere is the sundown sale at?
you never know who's doing the refurbs..... lots of companies don't manufacture the boards in-house, so they outsource the reburbishments as well.......http://www.soundsolutionsaudio.com/forum/index.php?showforum=48
its an intro pkg deal with their 100.4's but they are going to let their dealers put on a sale for the 1500's too.
Oh, and I had an opti2000, strong amp and cheap as a refurb, but hopefully their refurbs have gotten better, I was one of many that had problems.
