A no brainer? Not sure about that. Some people would be slightly concerned about putting in a knock-off amp that could potentially show up dead and/or die after a few hours of play. and unless you are VERY proficient in amp repair, you either have to send it back, or find a local repair guy. I don't know of anyone who has sent one back at this point. Then all of a sudden your cost is up to $1400, is it still a deal? And also, bro, 2,000 watts per channel? for a 100 dB sensitive speaker? do you plan on listening at 126dB's? EVER? I will give you 1,000 watts, that is ok with me. I understand crest factor and all of that, but 2,000? Not necessary, unless you plan on also using these to help you do the color commentary at your high school football games. I had my Triple12's running on a crownxls2000 and I could barely tickle the -20dB light at BLISTERING volumes and that was 750 watts per channel.
Yes, it IS true. And like I said, it didn't deter me from buying one for my subs, but in this particular case, I feel strongly that you could find another 4 channel amp (or dual 2 ch) that will come with full warranty and be enough power for your speakers. The 10Q's also have a much worse track record than the fp14k's.
