Problem i need help for pls:

(4) four wire conductor wires in an adjoining closet to fee the 5 speakers in the bedroom ceiling ( house i bought was wired but nothing labeled but all allegedly working per prior home owner

1 four wire conducted combined supplies the center channel speaker.

i assumed the other were for the front and rear but when i try the red and black or white and blue individually, thinking i would get one of the four speakers left, i got no sound. but when i combined the four wire speaker into two red/white and black/blue i would get sound out of both front or both rear. so i am confused. i hope this explanation is satisfactory for the problem, again any help greatly appreciated.

That's because the two fronts are connected in series, as are the back two.
You'd need 8 conductors to have them independent, not just 4.

Four 4-conductor cables would be a total of 16 conductors.

I think you just didn't try the right combination. If there are red, black, white and blue, possible combos are red-black, red-blue, red-white, black-blue, black-white and white-blue. Since there are 4 conductors running to a speaker that presumably requires two, two conductors aren't used.

Can you tell by looking at the end of the conductors which ones were likely to have been used before?
