you can put each driver on its own channel or bridge just the 8s on channel 1&2 or 3&4

Your setup is not ideal for that amp. The issue is that in order to bridge a pair of channels at 4 ohms you will be summing a mono signal into the two and you will not have an effective left and right channel. Unfortunately the best option would have been to get 4 ohm mids and bridge 2 channels for the right and 2 channels for the left then a second amp for the tweets.

If you get some passive crosses, you can bridge all of it together; provided you have 8ohm supers too. Does the 85.4 have active crossovers? How were you planning on crossing them over?

The thing about the 8ohm mids though is that they are ussually more sensitive than the 4ohm version anyway. So, even with them running at 8ohms, they'll probably be as loud as the 4ohms would be.

While that will work, in doing so you will lose stereo output. At that point you will not have left and right, just a mono signal.

If you don't care about having the balance left and right feature. Then just wire them together to get a 4ohm load. Yes this amp is active so you can bandpass them from 80hz-wherever your tweeters start.
