Summary: Incredible piece, lots of adjustability in sound, compact design makes it fit where other amps won't. plenty of power to run a average system, pushes a pair of 12" infinity reference series just fine. If you're looking to build a moderate system for your vehicle, you will not go wrong with this amp. Looking to build another system in the wife's HUMMER and probably going to use a KAPPA FIVE to run that system too.
Summary: I got this amplifier a year or so ago. I've had it in a variety of applications. At first, I liked it very much, but I could always tell that the sound wasn't quite there. I figured that the distortion must have been coming from my other components. Well, I've replaced everything besides this amp--CDA-117 head unit, K2 Power speakers--and the sound is still not there. This unit is a very compact amplifier. I hadn't realized this when I bought it.
Pros: Good for small spaces, looks cool, comes with nice terminal adapter for lower gauge wire.
Cons: Sound quality just isn't there, sibilance exaggeration, poor headroom on subwoofer channel (I have to have the subwoofer gain up all the way on the amp and all the way on my head unit with 4v outputs, and have the speaker gain turned to less than I'd like so that the subs can keep up) , questionable electronic filtering
good price but it does not work-lonfg wait to get support or anything

Summary: it's a 5 channel and high end series of infinity but the sub woofer output does not work (it does produce bass but barely audible compare other 4 chanles that I still hook up from the head unit. Called for support and get a run around that I did not know what I am doing. I did a test after talking to a tech by borrowing a 2 channel amp (cheaper than the infinity I paid for) from my brother-in-law's that I just installed.
Summary: Nice compact size and really performs! I have mine powering 4 6x9 Infinity Kappas and 2 12" Kicker Subs. More than enough power! It's quite a show piece too, with nice blue lights. I purchased it a month ago and has been performing flawlessly. A good investment and I highly recommend this amp!
The car amp came defective, sent it back to them and dont know the status

Summary: The amplifier came defective out of the box, I used to be a professional car audio tech, cable supervisor and electrician. I know my way around electronic devices, this amp as soon as I put power to it, it would cycle on and off quickly. I know its a factory refurb, but it should work better since they should have got the kinks out of it after it fault the first time.
Good AMP....had/solved Odd Issue other reviewer had
3 May 2011
Summary: I purchased this amp with high hopes. At first I was happy for about 1 week. After that, it went haywire. It kept forcing all the power to the front left speaker and the other 3 were getting fuzz. The problem was odd, but managable. You know how you can tell when your engine is warmed up when the temperature gauge is in the middle.........well, don't turn on your stereo until your car is warmed up, then it works perfectly fine with no issues 100% of the time.
Summary: This amp sounds awesome, definitely "loud enough". Sounds just as good as my old set up which was a JL 300/4 and JL 1000/1 with all JL speakers. Obviously the bass isn't as loud/ vomit educing, but it still is enough to be exciting. This thing is balanced with it's self so it sounds really balanced. I'm pushing infinity reference 6.5 components, infinity reference 4x6 coax, and a JL 8W7 in a sealed box.
