I went to an audio shop and asked for bass block, he handed me these capacitors:

100 MFD 100V

i'm using these on the stock speakers, are these the right ones?

i want to cutoff to be at 100hz

 

What you will need to do is wire the 100mfd in parallel, which is side by side, not end to end which is series,. When you do that that will give a 6 db octave 200hz bass blocker. To put it in prospective, for each 3db the power of that frequency is cut in half. so say they frequency of 100hz which is 1 octave or 6 db down from 200hz is effectly cut to 1\4 so low bass damaging the speaker is minimal.

What you need to do is to put them in series wtih the speaker's positve terminal, solder one end of capacitor to the pos terminal of speaker and solder speaker, wire the other end to the speaker wire. If you have any questions pm me, I will my phone number and walk you through the cap install.

 

what does a bass blocker do?

 

I'm not quite sure, but I think that you said to parallel the capacitor, then to put the capacitor in series, which are kind of opposites!

To block low frequencies you want the capacitor in series. Putting it in parallel would result in low impedence at high frequencies, which might be bad for the amp!

a 6 db crossover will work, but don't expect it to block all the bass. still, you will be able to turn your radio up louder without it distorting. if you are running an amp and subwoofer, i would definitely get a 12 or 24db active crossover. you can set the crossover points for bass and treble to whatever works for your car. that way you can crank the bass but keep it out of the smaller speakers.

 

im confused, heres the scenario:

the stock head unit powers the speakers, the 2 channel amp powers the sub, what i want to do is cut the bass off the car speaker @ around 200hz and below.

i just wanted a simple solution, i told the car audio shop and he handed me these capaciter, can't i just use them inline with the speakers? 1 or each channel?
