I want to add a sub but have no AV reciever


I have an HDTV in the living room but am not going with a home theater set-up. (That will go downstairs later) I would like to add a sub though. Is there any simple way to do this. Can I just buy a powered sub and attach it to my "audio out" on my TV and let the amp and cross-over in the sub do the work?

Thanks

Possibly.
1. Is the audio out analog (not digital)?

2. Can you use the audio out along with the built-in speakers that you are using now?

3. Can both the audio out and built-ins be controlled by the same volume control?

Yes x 3 means it is a go.

Some Sony TVs have audio out on TV controlled by TV volume control, most TVs do not.
Thanks Kal and Stanwal. I have a Vizio SV472XVT. I checked and yes to all your points.

Thanks again,
Chris
