Default wiring polarity

simple doubt, but


the wire is transparent , and one strand has a red line on it.
This is the one to be connected to the speaker + right ?

nah, when I got my ovals installed at motor plaza, the dude there was adamant that red went to negative. I had gotten the same dialog a long time ago

This dude was adamant about the wiring too, so i let it slide . But I just can't get the front/back balance right. And remembered about the phase of the rears being wrong.

Ok, now I'm sure . wil swap the wires

But i wonder how so many people can get the same thing wrong , and be sure about it.

just ensure that he connects it to same polarity on both ends of it. head unit/amplifier and on speaker. then it will be fine. some speaker wire of lower quality do have copper in one of the line and tinned copper on other, i suppose the copper one has to go to positive terminal in such case. ofc wires are copper colour on both so dosent matter either ways

Mostly There are two wires one in Red colour and other one is mainly Black (Sometimes Blue). Do remember that Red wire to the + ve point and the Black (or Blue) to the -ve point are connected.

I'm sure things are fine at the HU end, since i used a wiring harness, but the front - rear balance is weird. either I get all front, or all rear.
Not so bad, since I'm not bothered by the rear soundstage, but its still not right

Even if you use black for positive and red for negative, it makes no difference at all as long as it is consistent throughout the system.

It doesn't make difference when wires used as power source. But when the wires from Amp are being connected to the speaker they should be connected in correct polarity.

Why would it? Except in the case of very high end cables that feature networks in-line etc, there is no difference whatsoever between the two conductors.

Not sure about the amp but when I connect both the mid-bass drivers in inverse polarity from the cross-over, the bass doesn't seem right, as in, it isn't centred and appears to be coming from a distance.

@ greenhorn
For mid-bass drivers, the 1.5v battery test is the most reliable way out.
For tweeters, it's a bit more complex. Extended listening sessions might be required,
