Bought this amp when it was $300 and it is worth every penny then, now I see it listed at for a little higher an I'm a bit jealous now. If you're considering this amp I don't know if you can find a better amp for the price. I have both sets of my infinity perfect 6.1 speakers hooked up to this guy and they absolutely scream with clarity.
For those of you who have the infinity perfect 6.1 speaker and are having impedance issues with the speakers driving the amp into protect mode, if you do enough research you'll see that some of these speakers have impedance issues, maybe from the crossovers. But i have not had an issues with my speakers on this amp. I have each set wired in series so the amp is seeing 8 ohms a channel, but since there are these impedance issues, or whatever you want to call it, i dont know what the actual resistance is, but i know the amp has never went into protect and i haven't blown a speaker. Have the gain at 4V and had to turn the tweeter setting to -4dB. Hope that helps someone with the infinity perfect 6.1 impedance/clipping problem. I tried the Infinity Reference 475a and rockford amps and they all went into protect unless i wired in series and kept the gain really low. This amp should not have a problem though

This is an ok amp. Running a set of dls reference m6 with it. Doesn't get hot at all running at about 3 ohms. Don't know if i would use on subs though. deff not 2 ohms bridged gets kinda warm as is but does come with a fan right by the heat sink on the back.

I bought this and hooked it up with an 12" Alpine Type R. WOW. This thing puts out unreal power! Better than a Alpine 500 Amp with 2 type S's.

Boston gt series amplifiers are the best. Just compare the thd- distortion level. Also they have by far the widest range of frequency reproduction of any amp I have ever seen! And that is all you need for a crystal-clear extremely loud system. Buy these amps for subs and interior. U won't regret it.
