Question about Bose 901 VI Main / Stereo Speaker
Impedance is fine. Moving on...
I wrote most of this for a different receiver, but if you account for minor differences to your receiver this will work just fine.
There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.
The good news. I have a setup similar to what you want to do and it works great!
A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.
You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.
** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.
Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.
Write off the Tape Out as an input if you use it to extract the Front L&R channels. DO NOT monitor it or you'll chop the 901's out of the signal path AND kill any digital source audio in the receiver.

You might be faced with the age-old Bose issue of a 4-ohm speaker set. The ohm rating must be compatible. Most receivers drive 8-ohm speakers. If indeed they are incompatible, then it's up to you which component you want to replace (I don't recommend trying to find a converter to use the Bose speakers). The receiver sounds like it is new, so perhaps the speakers... or return the receiver and get one that can drive the Bose.

I contacted the Customer support folks at Bose. Here is what they said:
With a stereo receiver, the equalizer is run through the tape monitor section in the back of the receiver. The receiver's tape monitor output, left and right, runs to the amp input section of the equalizer, left and right. Then the amp output section of the equalizer, left and right, runs to the receiver's tape monitor input section. With a surround sound, home theater, type of receiver, the theory is the same, but the connection is through the preamp-out/ main amp-in section of the receiver. Not all receivers have this feature. Most, in fact, do not. Check the back of the receiver. There would be a connection made by two U-shaped clips. The plugs would be pulled out. Then connect from the preamp-out to the equalizer's amp input section; and from the equalizer's amp output section to the main amp-in. This effectively isolates the equalizer so that it is not affecting the other speakers in the system or the receiver's surround processing. Attached is a current list of known 901-home theater compatible receivers:

I have the list in a pdf document but do not see a way to attach it.

You're in luck because you have a full complement of pre-outs. You'll need a separate amp for the 901's.
First some background.
The use of 901's Active EQ (or any external proxcessor) in any digital AV receiver setup for anything EXCEPT STEREO listening through the 901's alone requires you to have a separate amplifier for them and to avoid having to use a Tape Monitor which could introduce proprietary and potentially damaging Active Equalization back into anything in the AV Receiver with its conventional speakers.
In an AVR, if you activate any Tape Monitor circuit at all, you will kill any digital sources. That is a function of AV receivers in general, nothing to do with 901's. Your Pre-Outs get us around that possibility and limitation but it also means you need a moderately powerful amp for your 901's. I use a Carver MT-200.
Run it with the Active EQ between the receiver Front L and R Pre-Outputs ** and the 901's amp channels. ** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then Bose EQ Amplier OUT >>> new amplifier IN.
Run it with the Active EQ between the receiver Front L and R Pre-Outputs ** and the 901's amp channels.
** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then Bose EQ Amplier OUT >>> new amplifier IN.
Then set the new amp's volume control (if it has one, mine doesn't) to something HIGH and leave it alone. Run through your speaker setup routines on the AVR. After levels and distances are set the AVR will be the boss of the 901's. With 901's don't even need subwoofers but they don't hurt. If you do have subs I recommend sharing the LFE with the 901's.
I've done this in my own setup once. Turn the 901's around so the rear faces point into the listening area. Crank up a movie like Master and Commander and when the waves are crashing or cannon are firing you WILL FEEL A BREEZE from them. Now THAT is multi-media!I advise having the 901's share LFE with any subwoofers you might have.
