Want to go full active, need crossover advice
Want to try going full active for the first time.
My system -
Alpine 9813 head unit
CDT M6 6.5" midbass (rated for 150W RMS)
CDT TW25 1" silk tweets (rated for 8W RMS - though I hear they can take 25W or more)
CDT TW19 3/4" imaging tweets (can't find what power is recommended, probably less than the 1" tweets)
Alphasonic PSW610 10" subs x2
Soundstream A4 (25x4 RMS) will power the 4 tweets.
Alpine PDX2.150 (150x2 RMS) will power the M6 Midbass speakers.
I'm having trouble finding recommended crossover points for the midbass and tweeters.
I was thinking about starting with the midbass playing from 50Hz-2.5kHz and the tweeters playing 2.5kHz and up.
Anyone with experience have any better ideas?

1st: Why so many tweeters? Is this in the S, and if so...where do you have them all mounted?
2nd: Your HP xover point looks good. I would start the midrange HP at 100Hz and work down from there (err on the side of caution...I can almost guarantee you'll have distortion at 50Hz).

Thanks for the reply. Yes, in the S. The 1" tweeters are in the stock locations. The 3/4 inch tweets will be in the A-pillars. I still have to take off the A-pillars to see how much room is behind them but I hope to experiment with different mounting locations before installing them permanently.
The idea is to raise the soundstage.
4 tweeters sounds like a lot to me too, but the extra pair will have a level control knob, and I can always turn down my amp gain if the high end gets too overpowering.
If this little experiment does not turn out well, I can always just pop the CDT crossovers back in with a little re-wiring.

Before destroying your A-pillars, I suggest looking into any of the 4 bottom tweeters here:

Just a pair of whichever you choose (I have the silk SEAS tweets in both my S and my truck) in the stock locations, bridge that 25x4 into 2 channels (prob still a bit underpowered) and see how that works. I bet you won't feel the need to raise your soundstage
