I just bought this amp as a refurb from DB-r electronics because I just could not pass up the price it was listed for. It's been in my truck for 2 days and sounds great on my subs. Any normal person would have no problem keeping it, but I am a very picky person. When I went to set the gains, I noticed a slight buzz coming from the amp when the gains were 3/4+. I set the gains for the amps rms(34.64 volt) on a 50hz sine wav with the HU volume at 3/4 and the sound was non-existant. Don't get me wrong, I am very happy with this amp at this setting and it absolutely pounds. But, it was not the amp I wanted to begin with. If need be, Chris from DB-r agreed to look at the amp and fix it if there are any problems, then send it to whoever buys it. But, I really don't think that's necessary. SOLD
