parallel impedence and different cut points

[Need-SQ 10+ year member]

I'm in the midst of an install in my good old 1997 Honda civic 4 door DX. I'm planning on mounting the 5.25" mids and 1.1" tweets of my three way

Alpine SPX-F17t's in kicks. However, I'd like another set of tweets up in the A-pillars, to bring the stage up a bit.

At the moment I'm planning on going all active and runing the current tweets off of the two channels of my Zapco Ref 350.2, which gives 100W X 2 into 4 Ohms, or 175W X 2 into 2 Ohms.

Could I wire and extra set of tweets (i.e. A-pillar tweets) in parallel and get 175W to each side?

And, if I can, how could I then increase the cut point of the A-pillar tweets.

I guess also, would crossing the kick tweets around 3k-3.5k and crossing the A-pillar tweets around 4k-4.5k seem like a reasonable idea? Thanks for any help/advice, opinions etc..........

Yes, that will work. Of course, you'll need a passive crossover on the upper tweet. That is a TON of power for tweets, BTW.

yeah I know. the tweets in the Alpine three way set are rated at 150W RMS. At least thats what the manual says.

from what I've heard the tweets are based on (pretty much the same as) the Scanspeak D2904/6000, which are also rated at 150.

I'm sure that they could take it but your ears will start bleeding at around 50W. Hella loud is my point.
