DYohn, it was the installer who suggested the amp, with much confidence even. I looked at the specs and said 'this is a two channel amp though.' and he was like 'yup'. And he explained the way he would do it, it was most likely the kind of crossover you mentioned above. I really think he wants to do one channel to the sub and the other channel to all the rest!!!
BTW the RF model is 3002 150x2 at 1ohm.
I think I will go elsewhere for the install, and probably end up going head unit to components and rear coaxial speakers, then just powering up the 12" with the quart amp I already have! Or else I could just keep the fac sys and use crossovers on the fac speakers, add the sub and amp which has individual gain and crossover.
at any rate, thanks everyone who offered advice, especially DYohn, I am learning alot and with any luck my ride should be bumpin by the weekend!

BoominRolla, that is exactly what the installer told me; the story about the 'wall of speakers' demonstration. It sounded overblown, and far too specific for my needs. It could be done ,yes, but you lose fade and the ability to adjust the sections of the system separately. The system could therefore be called 'all crossover' as that is where much of the adjustments are coming from. The 32 12"s idea is just a demonstration of what can be done, to show the amps true character. In real life, not flexible enough.
The installer was trying to save me trunk space, and I think he just had a hard-on for the RF3002 and he just wanted to show off this impressive bit of technical data.
A quick update, I went down to the shop this afternoon and had a long chat with another bloke that works with the installer who originally recomended the RF idea[who had left for the day]. He also brought up the now infamous Ron Trout training session, which these guys must use on alot of customers. So in the end I decided to go up to a 5 channel Eclipse amp(100x4, 500x1) to run the whole lot, so I can have more control over the gain of each section and it's actually a little smaller than the Quart amp I bought to match the sub so it does save space. the Eclipse RMS power output is only slighty lower in the sub section than the Quart, the other power matches my components and rear speakers perfectly.
Big up BoominRolla - don't shut up, you represented on that one!!!
