here is the situation, i bought a set of 4"infinities for the front of my cutlass and they came eith 2 capacitors.  since then i bought 2 different ones. 

can somebody help me choose the right ones. 

1. bipolar 100uf /50 v  hs-procon(i think these are the ones for the infinities)

2. non polar 100 mfd /100wv precision line

one of these is for my infinities so it will only allow the high frequencies.

the other one is for my 3-way pioneers to take out the lows and leave just the mids and highs.

i know this isn't the right way of doing things, but considering i dont have a crossover for now its the only way.

thanks

they are the same value... 100uf... they will both cross at the same point.... the only different is the voltage (power handling).... bipolar and nonpolar is the same meaning, different nomenclature

esentially these are the same cap and will both do the same job...

thank you for the quick answer.

maybe you can answer this for me also.

does it matter where the cap is connected(near the headunit or the tweeter)will there be a quality difference vice-versa.

if they are both the same value, putting this on my 3-ways will cut out the mids and lows also. thats not what i wanted. for the tweeter o.k. but for the 3-way if i just want mid/mid bass and highs should i get a different value cap.

thanks again

it should roll it off at around 400 cycles.... double the cap rating to half the rolloff point....200 uf to cross at 200 cycles (hertz)... for just bass blocking i would use a 400 uf cap........

alright, excuse my stupidity at understanding what you wrote.

so for the 3-ways i should get a 400uf cap, is this correct?

and again does it matter where the cap is connected(at the tweeter as opposed to the hu)

i am a noob at this, so again dont mind my stupidity

thanks

I would use a 400 uf cap and solder the cap right to the positive of the speaker.... i doesnt matter where in the circuit you put the cap but for continuity i always mount them right at the speaker (plus it makes looking for an open connection years later much easier if you dont have "mystery" items in circuit all over in the vehicle.....
