Bose lifestyle 50 systemhi, I have a lifestyle 50 with 3 sets of outdoor speakers all with an SA-3 amp. It used to function properly but now only the left side functions the right side is either very low...

Use only a BOSE cable. I used to have one and it was a pain when it came to the cables. Only worked with original equipment replacements. You can get your users manual from Bose in Adobe PDF format for free.

I have a Crest Audio V900, a set of Bose 901, a Gemini EQ-3000. Do I need a PREAMP? Or can I hook up the Crest AMP to the Equalizer?

You could use the EQ but it won;t sound as good as it will with a pre amp and also could make it a bit trickier when adjusting the volume and getting it to sound right.

How can I conrol the volume of bose sa 3 amp from the aux input ?

That would depend on the preamp. Name it. A true preamp outputs a variable signal.

It's not clear from the manual what the state of the volume output is without the VCA. Most amps default to full ON and the preamp attentuates the signal with a volume control. Try it with a signal that fades in slowly so you can intervene if it gets too loud. If it's full ON a preamp will control its volume.

Bose SA-3 amp and a non bose sub.. I keep blowing the amp..

How many ohms is your sub? The SA 3 Amp can only handle speaker(s) 6 ohms and greater. A lot of subs, as I understand, are 2 and 4 ohms typically. If yours is 2 or 4 ohms, then that explains it. The speaker would be "straining" your amplifier and blowing it.

I have a question first... are the 901's amplified by a separate amp as they should be in a multi-channel (non-stereo) setup?

Better yet read the following then decide if you have iy set up right to begin with. If so, I'd just treat the Ipod or Mac as auxilliary inputs on the receiver. :

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.

Bose SA2 distortion

As the distortion is on both channels it must be something to do with something that is common to both!
My guess is an IC. Check to see if it uses an IC for the main amplification. They are big with loads of pins coming out of them. Sometimes marked STK and then a number. If you find one it will have gone! Replace it with the exact part.

Bose amplifier does not work with a 6 speaker selector

your wall speakers may not be connected.... disconnect each speaker from the selector box and test with a small AAA battery to see if they are connected by putting the battery between each speaker's wires , you will hear it crackle ,then gradually connect each wall speaker onto the speaker connector box . If the first set does not work i suggest there may be a problem with your speaker selector box . Good luck
