HERE IS THE DEAL...

I have speaker wires coming out of the wall that have 4 wires (red, white, green and black). I can't find a wall plate with all four of these colors. I assume red and white are negative and black and green are positive. However, I don't know for sure.

All I know is there are two sets of wires each having the color scheme I described above. I simply want to install the wall plate and know which goes where when I plug them into my reciever.

Any suggestions would be appreciated.

Thanks!

The generally accepted rule is:
WHITE = left, positive.
GREEN = left, negative.
RED = right, positive.
BLACK = right, negative.

I can't find a wall plate that has all four colors. They all have 4 black and 4 red. Any suggestions? I appreciate it!

It doesn't really matter. As long as you have the negatives and positives lined up properly you'll be fine.

Just label your wall plate after you connect the wires. For instance label the top pair (the green and white wires) Front Left, the next one (the black and red pair) Front Right, the third row Center channel, etc.

There are only 4 wires. Red, white, green and black. No wire for a center channel. Any suggestions?

You will have to run a new 2 conductor wire from your AVR's center speaker connection to your center speaker's terminals, with or without a wall plate in between.
I don't have any experience with a wireless center speaker connection, if that is an option at all.

What exactly is this room layout? Most people have the front and center speakers somewhere close to the receiver and TV and dont need any in wall wiring.

Is this current in wall wiring for surround speakers?

Yes, it's CURRENT (already there) in-wall speaker that is red, white, green and black. The reciever being used is a Bose 3.2.1 System. It only has two "Audio Output" ports. The speakers that came with it have a DVI looking type of connector. I want to be able to use the In-wall speakers.

Not sure if it's possible.

http://products.bose.com/pdf/custome...ers/og_321.pdf

The manual is above. Page 13 shows a diagram of the back. I would also have to split the "Audio Output" to use all the speakers.

Please advise...

Most likely no. The Bose "receiver" is really only designed to work with their gear. The DVD player hooks to the "bass unit" and the speakers plug into that if I remember correctly. If you'd like to use the existing in-walls, I'd recommend going out and buying a new receiver.

Bose AV 3.2.1 Media Center.
The rear diagram is listed on page 13 in the manual.

YOU NEED A NEW RECEIVER IN ORDER TO USE THE IN-WALLS.

The 3-2-1 needs to be connected to the "bass module" and the speaker outputs from there are heavily equalized. So basically you could do it... but I wouldn't.

What you want to do and what you are able to do are 2 completely different issues given your current equipment. You may want to use in-wall speakers, but that Bose 3-2-1 unit is not designed to run any other speakers than the little cube speakers that come with it. It's designed as a stand-alone unit and not designed to be upgraded or modified. If you want to use in-wall speakers in a surround sound application, you need a receiver and speakers designed for that capability.

The Bose 3-2-1 system is designed as a simple to use plug-n-play unit that is suppose to simulate surround sound. It is marketed to the person who wants the home theater experience but who doesn't want to (or know how to) set-up a complete 5.1/6.1/7.1 speaker layout. Bose is known for proprietary connections that only allow the consumer to use Bose products. If you are happy with your 3-2-1 system set it up the way it was meant to be and enjoy it. If you want something more, you will have to spend more time and money to achieve that.
