Oh wow! Someone actually trying to be helpful. Can you make a suggestion on a pair that I might be happy with? What about Rainbow speakers?
Not sure why you wouldnt "believe" that I bought this amp. I'm running a JL13W6, Focal K2p's, and a Kenwood 7019 in dash. Those werent cheap either.
I also have 2 unicorns and goose that lays golden eggs...

How much for a golden egg?
Why not try some Boston SPZ60's

Right now I think you'd be better off if that goose pissed petroleum.....
As to the speaker question....how much are you looking to spend? Looking to buy local or internet?

Well... I've already spent a pretty penny on the Focals, and I was never really happy with them. So this is pretty much the last time I'm redoing this. I wouldnt be afraid to pay $1200 or so on a nice pair. But they'll need to be tough.
I'd love to be able to buy them over the internet. But I wouldnt know the first thing about installing them once they got here to Arkansas.

Think: Alpine PDX.
Small size, full range class D, JL just called it something else.

Found out that I had Focal 165 KF's (the ones that blew), not K2P's. Just bought a pair of K2P's for the front and some Polk db6501's for the back. That along with my 13W6 and Kicker 750.1 should be a pretty nice little set of tin cans...
Right?

FAIL ..bye, do some research before you post stupid comments. These new amps have some killer new features.
what makes it special:
I will assume you have a basic understanding of how Class D amps operate... If not, let me know and I will go back and explain that better.
There are a number of problems that make high performance in full-range Class D amps difficult, and you can band-aid some of them, but our method addresses all of these problems at once.
The answer lies in how you decide when to switch, when to change from one polarity to the other. Typical Class D uses a “blind” method – one that is ignorant of real-world problems and only works well if these problems don't exist. In other words, it says, “this should be correct”. (This is like a quarterback throwing a pass to where the receiver should be.) These real-world problems include non-linearities in the power supply, switching lag, pulse width errors, dead time, device non-linearities, etc.
A switching “cycle” in a Class D amp is a pair of rectangular pulses, one positive, one negative. The Single Cycle Control method measures the output continuously and makes the decision to switch, ending the cycle, when the output is correct. Because it measures the output, it takes into account all of the problems with changing supply voltage, delays, finite switching time, and so forth. In contrast to a “blind” method, Single Cycle Control knows that the output is correct. In other words, the QB can tell that the receiver got jammed at the line of scrimmage and adjust the timing of the throw to still complete the pass.
The output that SSC looks for is the area of the pair of pulses, actually, the area of the positive pulse minus the area of the negative pulse. This area IS the output at the end of the cycle, and it doesn't matter that various problems affect the shape of these pulses, as long as the area is correct.
SSC gets the output exact right over 400,000 times per second (once per switching cycle). It's as if you had problem-fixing feedback that was equally effective all across the audio band. It's elegant, and much simpler than applying a bunch of complex “band-aids” with the drawbacks that go along. The SSC approach is a bit more expensive to implement than the IcePower designs, but we feel the benefits are worth it as they really create what we consider a reference-grade product with all the efficiency and packaging advantages of Class D. In fact, I invite you to compare the sound of the HD's against any full-range amp at any price, of any type. They sound absolutely wonderful.
The HD's also have a more complete signal processing package than the PDX amps (variable slope crossover filters, preamp outputs, remote level control, polarity switch on the mono amp, infrasonic filter on the mono amp). And they're smaller than the PDX's by 15%, too (over 1/2-inch shorter in height).
HD's also feature a tightly regulated power supply with full R.I.P.S. implementation (equal power at any impedance from 1.5-4 ohms per ch. and with any supply voltage from 11V-14.5V).
Another difference is that our 600W monoblock is a full-range amp, which makes my inner audiophile salivate with visions of unlimited headroom.

I'm not exactly sure what that all means! But I'm sure excited about it!
