I don't know much about this stuff. I paid a pro to put a stereo in my truck that would make me happy. JDK sound and Security, recommended this amp with a Kicker 10" sub and Infinity Kappa speakers. I am very happy with it after about six months now. Really hits hard and clean!

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. The design goal for this is more than likely compact size, and not SQ. I just can't get it to sound good. This is a class-D amplifier--which is typically regarded as having much more distortion than AB or other designs. Class-D amplifiers are usually used for subwoofers because of this. Class-D amplifiers can sound very detailed and clear when designed properly. I was hoping this would be one of the well-designed class-D amplifiers. The class-D in this case was optimized for temperature regulation in tight spaces, and not SQ like I had hoped. The treble is often harsh to my ears--except during times with a relatively clear sound-stage, like a vocal solo. Mid-range is somewhat hallow, but this may just be because the treble can be so over-powering. Bass is punching, but not tight. When the sound-stage is full, this amplifier offers little separation--it sounds like everything is coming out of two speakers, and not pleasant to listen to. Overall, this amp could be good if you have no space, but not any good for serious listening.

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. If I turn it on before the car is warmed up (no matter the outdoor temperature) it does not work properly and force power to one speaker. Other than that, it powers my 12" sub and 4 speakers with no problem. My other components were professionally inspected and also everything was professionally installed, they said it must be the amp.

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. I do need to have the sub gain a lot higher than the speaker gains to get a balanced, bass heavy, sound. I'm guessing it's because the speakers are 2ohm and the sub is 3ohm. Or the fact that I'm using a small sub. Either way this amp is awesome and you will be impressed.
