Hi Penn,

Your best resource would be to ask Outlaw tech support for the definitive answer. Here on the forums, Search is your friend...

Here's a post with user experiences re: impedence and output running A&B, nothing on biwiring.

One thing to keep in mind would be Bass management. If you are planning on running a sub, remember that bass management is only applied to the A speaker pair. So definitely attach A to the top end (tweeters) as you describe.

Here's a thread on biwiring:

Good luck, and don't forget to let us know how it goes!
