Im installing speakers in my EG hatch...and i have no idea which wire is pos. and which is ground. The speaker sounds the same when its hooked up either way, so does it matter?

 

Truthfully.... no not at all. You would want to hook up the right way but sound Will come out either way. I dont believe there is a difference unless there is it a built in crossover or something else (neon light connected) that requires the correct + and -. just see how it sounds... wait... you cant tell the difference. What color wires are they? usually the darker one is the negative (black... brown)

 

It doesn't matter to the speaker by its self. What is matters to is the polarity of the overall system. Say you only have the front speakers installed. Now if you hook them both up correctly, then the speakers will both push out at the same time and pull in. This is called in phase. If you reverse one speaker, what happens is while say the drivers speaker is moving out, the passenger speaker in moving in, which is in a sense making the opposite sound wave of the drivers door. What this does is cancel out some sound, most of it being in the bass.

An easy way to tell if you have the wires backwards or not is hook them up (say just the fronts for example, or if you have rears hooked up too just fade to the front). Listen to how the bass sounds. Now balance to the left or right and see if the bass increases or decreases. If it decreases, then you most likely have the "polarity" correct. If it increases when it's only playing from one of the two speakers, and gets quiter as you balance back to the center, then one of the speakers is hooked up reversed in relation to the other speaker.

Now if you just go around and see between the speakers, compairing first the fronts, then the left front and left rear, then both rears, and then the right front and right rear, you should be able to get all the speakers in phase.

These guys are correct, but if it makes it easier on you, reds and blues are positives on those cars, and browns and greys are negatives. Good luck

 

Connect a 9v battery for a brief moment, if the speaker cone moves outward it means the positive battery terminal is connected to the positive speaker terminal.
