    I want to block bass to my 4x6s @ 300hz and to my 6.5s at about 150hz. What mf rating of capacitor do i use? do they have to be electrolytic? what if they dont have the exact rating, can i run two in series to get the desired rating? also what should the voltage rating be on them for a 23 rms/45 max headunit? thanks

    Bass blockers dont ususally work well. If you want to truely block the bass, use a capacitor and an inductor. Also, keep in mind the high amount of reactance around the 150hz range that you want to cross the 6.5" over at, your xover point will be shifted because of this.

    -what is reactance?

    what hz do you recommend blocking off?

    is an inductor the coil looking thing i see on passive crossovers?

    i connect the capacitor in the+ wire, where does the inductor go?
    thanks

    reactance is ac resistance basically.

    i would reccomend that you don't use any filter on the 6.5" woofers, and 300hz is a fine frequency for the 4x6's just make a second order filter using yes, a capacitor in series and an inductor in parallel.

    the inductor is indeed the coil looking thing.
