If the speakers work, even a little bit, it is probably not the speakers, but maybe a short in the wiring or loose connection somewhere, or the radio is going bad in those channels. I'd suggest looking for something loose first.
As for the windows. I'd bet that your master (driver's door) switches are a problem. If the window lockout is on, none of the other three windows will work with their own switch, even the passenger front window. Try that first. If the passenger works without the lockout on, then it's probably the back switches. You can unplug a switch that works on the master and replug one of the back windows plug into that switch to see if the switch is bad or not. I bought switches on ebay, they aren't too bad to get a new master. But you can figure out if the two switches are bad just by using the good one as a test. They are pretty easy to take apart and move around.
