HELP -- house with built-in speakers.

[txhorns]

Hello,

I just bought a house that have speakers built-in and pre-wired for around the house & patio. So I have 6 different speaker wire cables (the 4-in-1 type with red, black, green & white) coming out of the wall by the entertainment center. The cables are not marked so I don't know the polarity for the speaker pair or the room assignment. My question is:
* Is there a tool where I can identify and match the wires to the correct speakers without hooking up the wires 1 by 1 to the receiver to test it (assuming that the wires and/or speakers are functional)?

Thanks.

Red & Black = Left (red = positive, black = negative)
White & Green = Right (white = positive, green = negative)

In a normal wiring hookup the above is correct.

To test, you can use a 9 volt battery and just touch the wires to it which will create a little bit of noise on each speaker. Shouldn't harm any of the speakers. You can also get a test tone producer, but that's a bit pricey if you don't own one already.

You probably should consider a speaker selector that does impedence matching or make sure the volume controls are impedence matching before hooking them all up!
