Which end is postive on capacitor???

I have these capacitors in my crossover:

I now have them built, and I'm wondering if I have them going the correct direction.

Is there a "+" and "-" to this style of cap?

You should be using NP caps, which do not have a + or -

If they do have polarity, they're marked rather clearly.

Polypropylene capacitors are non-polarized. You can use it in either direction.

Those are metallized film polypropylene capacitors- they do not have polarity, and you can connect them interchangeably. Electrolytic caps come in two versions; most are polarized, but NP types exist which are actually two polarized caps connected back to back. Not really a very nice way to make capacitors.

Thanks!!!

Thanks to all, and this is good information for others that may have the same question.

I thought that was the case, but I was just checking to make sure.

For sure, I was just freaking out that my built and installed crossovers had the polarity incorrect. I havnt cpompleted the speakers yet. Came across this post and now I can relax. Thanks

LOL. I'm glad that this was helpful for you!

Make no bones about it, I'm no spark and wires guy, well, I'm a sparks guy, typically when I have it wrong!!! I absolutely know just enough to be dangerous with electricity!!!

Have a great day!!
