SDA 2b Wiring

Hello,
When I bought my SDA 2bs the outside speaker in the right cabinet was unhooked. I connected it the same as the mirror speaker in the left cabinet regarding which lead is connected white/ greeen. (Stupid or not) I have been running them like that for a month, maybe an hour or so at a time.
Recently, after about 3 hours of playing I got a medium pitch "noise" from the speakers. My son said the noise started coming and going and then stayed constant. My setup is a vintage pioneer amp with preamp out run through a vanalstine amp. I could still hear the music behind the noise, and volume still affected the music up and down, but not the constant noise. After a cool down, everything is fine, speakers amp, etc.
Did my stupid wiring decision cause this problem? The speakers were fine for several listenings, maybe I didn't listen to them for that long at one time.
Now I'm scared to use the SDA's with that amp. What should I do?
Thanks in advance for your help. Gary

How do I tell positive from negative on the drivers. Sorry for the rookie questions!

I had the same questions. Black wires are positive. There should be a painted red dot on the positive terminal of the driver. Should is the key word.;) -
Do you know for certain whether or not your amp is a common ground config.? A must for SDAs.

Black or blue is positive. Green or white is negative.
You need to check that your amp is common ground as what you are descrbing would indicate to me that it's not.Political Correctness'.........defined

I'll look again, but the positive or neg on the drivers is the key. I have the wiring diagrahm but didn't see the difference between the pos and neg on the driver itself. I'll give it another look... thanks for the help everybody.

Frank at AVA said it was common ground, but maybe I was not asking the right question... I'll try him again.
