Can I get a center speaker out of my 2.1 setup?

Just a thought I had. Don't know much about speaker wiring. Wondering if this would harm anything?

Not entirely clear but not likely. You cannot connect the outputs to the L/R speakers to each other to make a "center" channel. Also, by shorting them together, you will lose any separation between L/R and all speakers will play mono.

Probably saved your amp, too. I’m pretty sure that shorting two output channels together (which is ultimately what you’re accomplishing) will do nothing good for it.

I cannot be certain but it looks like he is splicing amp inputs.

What receiver or amp are you using.

If it has pre outs/main ins you can do what I did in my secondary room as I had an old amp laying around.

Pre outs to outboard amp, outboard amp in mono bridged mode back to receiver which drives the left and right.

Added a center speaker with the outboard amp that plays in mono.

Works well in 3.2 and to listen to music in stereo just turn the gain down on the outboard amp.

Although it was written about car stereo, the methods described in this article can be used at home too:

Just to be clear. You can derive a signal for a center speaker but it is not really a center channel source. If it works for you or you need it, OK.

What are you trying to achieve? A center channel in the AVR world is in itself another channel separate just like the keft or right channel of a stereo. It carries unique information to it alone along with common information from either left or right channels or both left and right.

You cannot just connect stuff up and call it a center channel. You must have the receiver that can process the center channel separately from the L&R channels. In order to do this, you need a 5.1 channel home theater receiver and a source that has the channels encoded separately. If your receiver is just a stereo receiver, forget it, because you won't end up with what you want (but you will probably end up with a smoking and dead receiver).

It's a VIRTUAL channel unless stated otherwise.
