Boise can i hook my boise 321 to route my tv speaker sounds thru my boise speaker on my new samsoung tv need to find a way to connect my bose gs system to my new spectre 46 inch tv. TV has no yellow video in spot. My bose unit is an earlier one and has no HDMI port Thank you

The Bose 321 have an optical in port for external media.

Is the sound output of the TV set to mono?

Hello, its always better to go the shortest route this would be ps3 right to the bose there are too many menu variables ,circuits, that would be involved if you involve the tv output as well. that theory applies to video as well always go directly from source to load without any additional switches (circuits) when possible.

You should be able to connect the bose directly from the cable box. You also can connect from the audio output of the TV itself providing it has an audio output.If all eslse fails you can use the headphone output from the TV to the input of the Bose system

If your TV is HD, you should definitely be connecting the component video cables (green, blue and red) from the 360 to the TV (the 321 will not do video pass-thru from component cables). -Make sure you have a picture at this point. (TV switched to whichever input you connect the 360 to)
You can get an RCA extension cable for the audio portion (red and white) to connect to the 321 for audio. You could also connect an optical audio cable to the 321. An optical cable must be assigned from the system menu to work..
Let me know if this helps.

Go to menu, select language choose appropriate language.

yes you can.
just have your audio out from your tv going into an audio input on the bose system. 

No. You would need some kind of audio out connections on the back of the media center. The only audio outs it has are the
Acoustimass® Module – SPDIF connector.

Unless you were to hook up an amp before the Bose media center. In other words, you could run your TV to another amp's line in. You would hook up additional speakers to this other amp, then run audio line outs to the line in of your Bose media center. Some stereo amps have a line out or record/tape out, it is from here that you would run the cables to your Bose media center line ins. The disadvantage to doing it this way is you would have to plug all your media devices (dvd, tv, etc) into this amp first and your Bose remote wouldn't let you switch between devices. If your media devices you have offer digital audio, then you would want an amp that also offers a digital out for the best sound. Otherwise you will end up with analog out from this amp to the Bose media center and thus lose any of the digital signal information like surround information. So there isn't much point in doing this. If your gonna get an amp that has all the digital in's and out's, you might as well just use it with new speakers and forget the Bose system you have.

You will need a Component Video Cable
Connect the Red Green and Blue Connections from the TV to the Bose.

if your audio is coming from the TV, also connect stereo audio from the TV's audio out to the "TV" input on the bose.

if you want to hook up other devices (VCR, BluRay, etc) the video will go directly to the TV and audio will go directly to the Bose

I had my older bose 321 hooked up through vcr and sounded great. Then hooked it up through directv receiver and sounded better. then switched from direct to comcast and hooked the bose up throught the comcast hd receiver and the volume is aweful. same deal, have to crank it up high. Since the stereo built into the tv sounds so much better I disconnected the bose and am going to sell it.
