With a 2 channel amp that sends 75watts rms at 4 ohms x 2, how would you wire this tweeter and this mid-driver at 4 ohms (if you have 2 of the tweeters and 2 of the mid-drivers, 75watts to each side)? Note: the problem is that the impedance of the tweeter is 6 ohms.

The problem is not a 6 ohm tweeter... It's you need to design a passive crossover or I would use an amp or pair of channels for tweeter and midbass with active crossover.

Madisound designs or builds and a few sites will design or will instruct you on passive crossover design. Madisound (www.madisound.com) or Solen (www.solen.ca) can sell you the components to make it.

But, with both drivers at 90 dB sens, I'm sure you will find running the tweeter at 56 watts and midbass at 75 watts will not be an issue. I would not be surprized if you still have to cut the tweeter by about 3 dB to match with the midbass. Your midbass needs power but your tweeter does not and should keep up just fine.

I already have two passive crossovers, crossover point is 2500hz. It says their is selectable attenuation for the tweeter level, but I don't know how to do it...

There is probably a switch inside of the x-overs. I'm using those tweets with some Vifa PL's and have them attenuated by -3dB to best match them to the mids. That should be a very nice sounding component system.

Do you know if the crossover was designed for a 6 ohm tweeter?

If not your crossover frequency may not be 2500 Hz at all.

It's possible to look at the value of the components on the crossover to know crossover type and resulting crossover point with a 6 ohm tweeter. You would need to look up a network table for the crossover type and you will know your crossover point.

If the crossover was designed for 6 ohm tweeter well you have 2500 Hz, which may be too low, but you should be able to match your tweeter to your midbass in terms of volume.

Anybody have any ideas as to whether these peerless mids and vifa tweets (links above) will sound compared to the new focal access components (165A)?

Just as good is my guess
