Please do for the rest of us as well, just waiting for the first of Oct to order mine.
Sorry SF sometimes I get carried away with my acronyms assuming everyone here knows what I'm talking about. Yes the Power Acoustik RZ4.2000D. The RZ4 is 2 and 4 ohm compatible. Run the RZ4 from the fairing location on top of the radio. Reduce the gains a little on the infinity's and turn them up some on the Pioneers. No problem running two and 4 ohm speakers on this amp or any amp that's 2 or 4 ohm compatible for that matter. Run the infinity's on the front channel and the Pioneers on the back channel. No need for two amps on a four speaker system. Bottom line is you can definitely use the RZ4 for the infinity's. Trust me you will love it!
Sidebar: I'll be installing that amp/speaker combo in a couple weeks. What did you set the gains at? What did you set the crossovers at? Fronts will be high pass, but do you run the rears full range and adjust with the head unit?

I always look at my gain setting like the face of a clock. On the infinity's the gain setting on the RZ4 is set straight up and down or the 12 and the 6. The Pioneers are set at the 1 and 7. You can run on the infinity's on flat as well. Flat meaning All Pass or full. . If you use MP3gain. You can set all your music at about 93db and not worry about clipping. Sounds dam good by the way! This amp does not have a crossover setting. That would be accomplished through the HU if needed. The frequency response on the infinity's is 45-25k HZ So you can cross them over at 60 to 80 HZ without a problem.

have you tried both? I am willing to buy a set of pioneers just to see the difference I am sure I could sell one of the 2 . Would I need to water proof anything if I use the lids from BT?

I dialed in the RZ by ear (after using my o scope to see where it would clip with 50 Hz / 0 Db test signal)
As I can recall BOTH channels are set to between 2 and 3 - or 8 and 9.
My HU volume goes from 0 to 62! andf I hate it to go all the way to 62 to get the max out of it. So I dialed it in by ear around 40 as "max" without distortion.
I use the fader to move "power" more to the back (running +3/+4 to the back). Keep in mind you are NOT moving power (Watts) from the front to the back or vice versa... it is basically reducing volume on one set of channels (L/R front or Back; wherever you move away from on the Fader).
both channels on my RZ are set to AP. I did play a bit with the HP on the front but decided to give the Polks all the music got.
the gains on amp is - when using line signal - just how far you are willing to turn up the HU volume to get to the point where you reach your max volume you will listen to. Line signal will NOT distort, unlike speaker signal from HU.
so when dialing in a Stock HK HU and using speaker outputs, you will need to put the volume around 50%, as that HU will start distorting around that point.
and yes - as Gannicus stated - use MP3Gain to level your music at the same "volume". it will also remove "clipping". I started reading up on the technology they used to determine the clipping etc. Then I kind of gave up... although I would understand it, but what's the point right, if it works...

use some hydrophobic fabric (expensive) or my way (way less expensive; see my hydrophobic forum thread in the audio section) between speaker and lid.
