Tweeter Wiring Positive and Negative?

[SamuelBC]

Hi All I've installed Audison AV 1.1 tweeters in my car and it has a striped red wire, is this positive or negative?

I wired it up as the red stripe being negative, however I've read conflicting reports online as to if a striped wire is a negative or positive.....

Please see attached photo of my wiring.

This is what I found about red stripe being negative (as I had already thought).

This is referring to red stripe being positive....

As that link says, you can experiment with the electrical polarity of the tweeter to get the best acoustic results depending on tweeter positioning in the vehicle.

Thanks mate, however how would the manufacurer have intended for it to be installed?

The owner's manual just shows a red wire as tweeter positive:

Often the positive terminal on the body of the tweeter is marked with a + sign or a red dot.

You could also look to the wiring of a woofer to see which wire is connected to its positive (+) terminal.

At frequencies above the 2 kHz crossover frequency of your tweeter, phasing is of little importance, particularly in a car where the tweeters and woofers are not concentric with, or located next to, each other. Again, you can experiment with electrical polarity to achieve the best acoustic phasing.

Alternatively, on a tweeter, the smaller terminal is usually the negative, and the larger is usually the positive.

Just like on this woofer (smaller, negative terminal indicated with an arrow).
