Even if you switch the pos/neg you will still get sound, it would just be out of phase. Try hooking the original speakers back up, and if they work, I would think there is a problem with the pro 80s themselves. You could also use an ohm meter between the inputs on the pro 80s and check to make sure it is not "open". I beleive they are 4 ohm, so that is what it should read.
