Waterloo,
What model Polk amps did you install? I've had my eye on the PA5000 5 ch.class D for awhile
Did you bridge the amps?
Very difficult to get accurate power ratings on car audio. I look at RMS power/channel, THD, Signal to noise ratios. High power amps with lots of overhead available power pushing 10 watts RMS of clean power is enough to blow most people out of the cab.
As far as head units, Alpine, Kenwood, Pioneer are all top shelf.

I have 4 Polk speakers on my home system that I bought direct from Polk as refurbs. Couldn't tell the difference between new. Very happy with them.

I'm interested in what you did with the speakers.
