In which case the midbass can do well down to 63hz at 24db octave slope going upto 6000hz with 12db or 24db octave slope. As per the power, feeding them with upto 90-100RMS should be good. 120RMS might be a lot for them.
Tweeter rated at 20RMS I suppose can be crossed very low from 1400hz and above at 12/24db octave slope, the FS for these stands at good 790hz with freq. response of 800-45000hz.
Running these active would give a good flexibility since as per the mounting you can make either the midbass cover almost complete vocal part upto 6000hz and 6000hz above can be handled by the tweeter OR You can run the Midbass doing 63hz at 24dbslope to 1600hz at 12db slope and above this point can be done by the tweeter, but since it is rated at just 20RMS I guess best would be to figure out which setup would suit better as per your car's acoustic.
Options are many with both these midbass and tweeter as they have very good flexible freq. response and T/s parameters if you plan to active with them. I had read somewhere on some forum where some have used the midbass in both passive and active form and have stayed with running them Active and with the digital crossover on the Eclipse you could have more precise freq. points and slope. But, somehow I have feeling that running them active won't make much difference compared to passive in context to SQ from them, may be little better midbass response with active.
Would like to see the install happening Frank let me know when it does.

thanks abhi. i had read all this from the same source you read, but let me tell you that my amp for this set is
just about enough power! There are people who are feeding an ENTIRE PDX 150.4 in active mode. LOL.
Another interesting tidbit for everyone. AS you'll must have noticed in the schematic diagram of the cross-over, there is a 20W
OSRAM electric bulb built into the crossover, that lights up whenever there is an excess of power going to them.
people giving 300W each side, have still to see the bulb light up!

Make that 130-140W now ;-0
