Contour Enthusiasts Group Archives Forums Modifications Audio Capacitors ?????

I just bought a pack of four 199 MFD 10%/100 WV Capacitors. I thought you only put one in line on the positive side of a speaker.(To kill low HZ from going to my 6x8's in my doors)

The package says to put one on EACH wire to 1 speaker? Was I told wrong???Will it not work just on the positive??Or do I have to hook them up to both wires? God I hope not at $5.oo a pop, I'll go broke???Thats $40 total. I mine as well EQ the speaks for another $40....

Any body have caps on thier door speaks and could ya give me any info on how they sound and what specks I should look into? I want to kill the bass throb at high volumns!!!!
Thanks guys....

Are the 4 I bought worthless to me, or can I use them????

I thought Caps were used to help the amplifier boost low signal power spikes that the amp couldn't handle. The high powered transient spikes that drain amp power. They recharge and discharge quickly,helping the amps when high dynamic loads are present. I think what you're looking for are bass blockers......

if your intended use for the caps were to protect you door speakers from low bass you have the correct capacitors. assuming your speakers have a 4ohm nominal impedence your 199mF cap. will provide a 6db/octave 200Hz cutoff. as for the wiring make sure the caps are non polarized and just connect one (1) to the pos(+) terminal on your speaker. the (-) terminal does not need one, so for 4 speakers you just need 4 caps.

Thanks David-
Thats what I had thought its been about 7 years since I had messed with upgrading stereo equipment.Now I can block that terrible speaker damaging BASS to the dorrs.....

Bass blockers ARE capacitors, just a different type/size used to a different purpose. Capacitors are devices that store energy and release it in bursts. The obvious use of this is what you mentioned about keeping juice to your amps, giving them a nearby reserve or power.
caps also by function pass a/c but block dc, by using a cap of the right spec you can filter low end signals as they will be seen as d/c by the capacitor. This is opposite the funcion of an inductor, which will block high signals because as the voltage increases, so does inductive resistance, when the resistance is too high, voltage will no longer pass through.

(type/size,value of these components are what determine db slope and crossover frequencies)

I'm pretty sure I typed all this right, but I'm kinda tired so..
