How do I add sub woofers to my Bose 901system? I am using a Marantz 2285B with plenty of power and have a seperate speaker output but will the Bose equalizer allow the subs to perform properly. I also have pre-amp outputs I guess I could use for a powered sub system.
You would need to use a modern equalizer like the EQ901 PS which has a built in crossover and four outputs. This would be connected in the pre-out / main-in loop of your Marantz 2285B.
The Bose system has sound that is unmatched, the 901 with the equalizer is amazing. I have done what you are thinking of doing, the speaker runs 5ohms giving more power to the coils, adding a sub will color the sound and will not give the desired results, the 901 equalizer may be damaged with the modification of the sub, not recommended.
Testimonial: "Thanks for your input and I agree that any modifications to the 901 equalizer and its function would be bad, but I am going to attempt to keep the subs out of the 901 loop by using my pre-amp out siginal with powered subs, do yu think this might work."

You may connect an additional amplifier to the Rec Out or Line Out from your existing receiver.
Please note the Bose 901 equalizer can be used to connect to one amplifier only.
Do let me know if you have any further questions.

i, trying to hook up a powered subwoofer to my hafler dh 110 and dh 500 running a bose 901 series v active equalizer and series v 901s any info would be appreciated

There is no direct connection between the 901's and their Active Equalizer. It is designed to be inserted between the source and the DEDICATED amplifier driving the speakers. Typically, this would be in a Tape Monitor loop on a receiver.
Tape Rec/Out to EQ In; EQ Out to Tape Play/In on the receiver. If you have a tape deck(s), it(they) would go into the back of the Bose EQ as if it was the receiver and you would use the Tape and 1/2 buttons for selection.
Or,if you have access to any other point that doesn't use the Tape Monitor, like a Pre Out/Main In jumper set, place the Equalizer there. That way it's always in front of the speakers and doesn't take up the Tape Mon.
Flip in the Tape Monitor and leave it on or the speakers will not receive the essential ACTIVE Equalization they require for proper frequency response. DO NOT place non-901's onto any amp using the Active EQ.
Like any speakers, the 901's will attach to the speaker terminals in the conventional manner.

I had the same problem- I have a Pioneer VSX-518 and Bose 901 series IV. My receiver has no "Tape Monitor", so after trying different hook ups, I went and bought a "3 input video switcher" (about $10.00) I run my STB (cable box), my PS3 and my computer through the inputs of the switcher (just the audio L/R) then the output to the Bose EQ input, then from the Bose EQ output to my receiver input (I chose to use the TV/DVR input). Now I just have to select which source I want to listen to from the switch, make sure the receiver is set to TV/DVR and I have fantastic sound via my Bose 901s. With this hookup, I have my 3 componets video connected to my HDTV via HDMI cable. It works for me. Hope this helps.
"CAUTION: Make no modifications to the system or accessories. Unauthorized alterations may compromise safety, regulatory compliance, and system performance."
That warning is not in the manual to just protect their market share. Even if you succeed in making the desired electrical connections the results may be less than stellar.
I'm not saying this IS the case but here is some Food for thought.
Bose's main claim to fame, the 901, was always based on achieving flat audio response from full-range speakers (NO WOOFERS or TWEETERS in the case of 901's) through the use of large amounts of prioprietary equalization applied to the audio signal. Another evolutionary step way in Bose amp/speaker systems was to deviate, sometimes drastically, from the 8-ohm speaker driver standard and design the mated amp to work with the selected load. THAT is just two reasons why no specs are published for the sub-parts of any BOSE SYSTEM. It's a system.
In the mix n match world of COMPONENTS specs are published so one can choose a given speaker for use with a given amp and expect electrical compatibility, frequency response and power handling.
Except for standalone passive speaker systems, mixing and matching Bose speakers with third party electronics (or vice versa) is discouraged as being potentially dangerous and at the least sonically unwise. For example, if you've ever heard how a Bose 901 Active Equalizer sounds with non-Bose 901 speakers you'd understand.
Maybe someone else can fill in the pin-outs of the cable and chime in on whether or not Brand X speakers will work with the Cinemate amps. Not knowing what other brand/model you're contemplating, it would be impossible for anyone to offer a qualified judment on that score.

I agree that any modifications to the 901 equalizer and its function would be bad, but I am going to attempt to keep the subs out of the 901 loop by using my pre-amp out siginal with powered subs, has anyone attempted this?
