I Have A Customer Who Purchased A Regular L/r Outdoor Pr Of Speakers And Wanted To Place Them On A Seperate Patio, Trying To Use 2 Spkrs For 2 Patios W/o Having Stereo Spkrs. I Already Had A 4cond Spkr Wire On Each Patio Just Knowing They Would Purchase What I Suggested. I Used The 4cond And Connected Red & Black On The Positive Terminal, And Used Green & White On The Negative Terminal. At The Receiver Is There A Way Using How I Wired The Spkrs Outside To Make These L/r Ch Spkrs Sound Mono?
