Any suggestions as to what's wrong and/or how to fix it would be greatly appreciated.
P.S. Yes, I have rechecked the connections many times, but don't see anything wrong there.
I'd check the speakers by putting it in different positions in your car and if you have the same result, it may be your headunit or your wiring may be cut or shorting out somewhere. I'm assuming you're running those rears through an amp. If so, check the input gain on your amp. Regarding the static, use a ground loop isolator. If that didn't work, check your wiring again.
