(I am talking about the small wires with a buldge in the middle that are supposed to block low frequencies)
I just bought some of these because when i turn up the bass on my head unit my speakers sound horrible. The two wires leading to the speaker aren't marked so i cut the brown wire hoping it was the positive wire. Then I connected a passive crossover within that wire and i turned on the head unit and no bass was blocked. So i cut the white wire, connected the brown, and did the same thing to the white wire. But still no bass was blocked. Am i missing something? Cuz it isn't working and i was beginning to get really tweaked. Any help would be greatly apreciated.

Probably says 800hz @ 4.0 ohm and 400hz @ 8.0 ohm and would be a 50uF capacitor.
This should be totally suitable for your driver so if you are still having problems with it bottoming out on bass I would suggest lowering your bass boost and adding a subwoofer.

I figured it ment 4.0/8.0 ohms because i have never heard of the resistance being over 12 ohms. But then again i am just getting into car audio stuff so i thought i may be wrong.
I am getting a sub, i thought that this crossover would stop all bass going to my speakers so that when i turn up the volume my sub would handle the low frequencys and my regular speakers would handle my highs without bass distortion. I thought no low frequencies would get through even if i had bass boost on. Thnx alot for your help.

Ah. No, a crossover has an attenuation rate to it referred to as 'slope'. In your case, a cap on it's own is only 6db per octave so while it helps, it does not attenuate the low frequencies very much.
You would need a more complex crossover with a steeper slope to attenuate the bass frequencies more.
