To get the 6.5" speakers in the factory locations you have to trim about 1/2" of metal all the way around and there's plenty of mounting depth if you remove the foam piece that backs the factory 5.25". I used a drill with a 1" hole saw extension to cut a hole directly into the plastic factory kick panel so I could mount the tweeters there.
As far as power requirements, well I'd try to put at least 100 watts on the Q Series and 150-200 on the Stealthboxes. That's 150x1 or 200x1 @ 4 ohms. The Stealthboxes for the E36 are 2 8" 8 ohm drivers that when wired in parallel present an amp with a 4 ohm load. No need for a 2 channel amp. One last thing - IMO you could do waaaaaay better than Rockford for amplification. And that's putting it mildly.
I'm not sure Rockford Fosgate would even make my top 10 list. Try Xtant, Zapco, McIntosh, PPI, a/d/s/, Linear Power, US Amps, Brax, Genesis and if you must go mainstream then Phoenix Gold or Kicker.
: You can mount the 6.5 in the kick and recess them so the grills mount flush. It isn't easy, but it looks great when you are done. Put the tweeters in the door where the factory tweeters are. There just isn't room in the kick. I am running 2 90W amps. Rather than doing the board up under the backseat shelf, I put both amps back2back on a board and mounted them vertically tucked into the left side of the trunk. This is great because you can still get long or tall items into the truck. I like the JL audios in the back. I get great fill for my application. If you have the windows down, the bass is much diminished though.
