Default Does it make any difference if you hook up the wrong polarities on the speakers?

Reason Im asking is because I didnt know which wires were what when I put in new door speakers (Infinity KAPPA 63.5I). So I took a stab in the dark and was thinking with common sense in mind ok lets see usually the darker wire is negative or usually the silver connector is negative and went with that.

If I hooked it up wrong can it hurt anything it seems to sound fine, I just dont want to take the door panel off again and rewire it.

Thanks for any help.

As long as u stay consistant amongst all of the speakers in your car, it wont matter, u'd be able to hear the difference in speakers if one or two were hooked up backwards, because the sound would cancell out itself because it would be outa phase, so it would sound very weak.

Exactly right. Electrically, you won't hurt anything, but the sound quality will suffer if you're "out of phase." By reversing the wiring, you'll have some speakers pushing while others are pulling. The speakers themselves don't care which side is (+) and which is (-), you just want to be consistent on all speakers.

If in doubt, go in and switch the wiring and listen for what sounds best, or there are test cd's that will play a tone to check if you're in or out of phase. The test cd will also clean your head unit so it's a good investment. I picked one up at Best Buy for about 12 bucks.

sorta.

yes if you stay consitent it wont be out of phase but the sound quality will still not be 100% the reason is that the music will be pushing inward on the speaker when the music should be pushing outward. not everyone can tell the difference but it does sound a little better if you have it right.

P.S.
Best Buy sells the speaker harness for our cars for 6 dollars. they are model # 72-9301

The good thing is... even if it is all backwards as long as everything is the same then it shouldn't hurt anything.... however this site I have a link for needs to be updated but it should help a bit.... http://www.installdr.com/

Thats not true, it won't affect sound quality at all. No one can tell the difference, as long as all speakers are connected by the same polarities.

There IS a difference. The sound being broadcasted is meant to push a speaker one way or the other. If they are hooked up correctly they will play the way they should, the way the music was designed to play. Yes it does sound similiar, is there a difference? YES. Or y the hell would they even take the time to label the speakers.

They take the time to label the speaker terminals, so consumers connect all the speakers with the same polarity.
In fact, most x-overs in car audio applications already have their polarities reversed to compensate for a misaligned phase, not to mention that inductance alone causes polarity changes.
With that being said, I doubt your speakers are even in absolute phase, unless you have tested and corrected for phase delays( I doubt you have), which only hard core audiophiles do, and IMO doesn't make any audible difference.
And since a speaker vibrates many times a second, I don't believe your ears, or anyones for that matter, can tell the difference between polarities, given that all speakers are wired in the same polarity.
And the signal being reproduced isn't meant to push a speaker one way or another, a speaker is linear and it's only designed to push a speaker outwards when the driver reproduces the signal.

1. i personnaly do and have checked phase in every car that i work on with a tool designed specifically for it. and yes it does work.
2. hook a speaker backwards and try playing sound thourgh it and you will notice that it does not play at its peak potential.
3. Your right it is very difficult, though not impossible to tell the difference if all speakers are wired backwards.
4. I dont care to argue this point anymore, im not here to argue and bicker. Ive said my peace and so have you.

The big one goes to the golden wire, the small one is the silver wire. Positive Negative respectively.
