I just installed some speakers and stuff in my room and some speakers are not marked with a positive or negative, but they sound about the same when hooked up either way (positive to positive or positive to negative). One is grey and one is black... Is it bad if I have them hooked up backwards or does it really matter?

it does make a slight difference, but its ok as long if u have more than one, they are all hooked up incorrectly the same way

It's called running it out of phase, and it affects the sound. If the sound sounds like it's coming out of the sides of the speakers and not the front when you are at the listening position, then you are out of phase....
