Parts Express 80 Hz High Pass 4 Ohm Crossover
I have connected active subwoofer with low pass filter to my standart car audio system (4x45w 3 Ohm JBL GTO 529 speakers in doors). I want to cut low frequenсy from each speaker around 100Hz. So i need 4 pieces of this model ?
Yes you will need four of these filters.

I'd like to keep frequencies < 80Hz away from my MTMs (I have stereo subs in parallel). Would the best way be to wire this filter downstream from the woofer taps on the existing MTM crossover board, or ahead of the crossover? The MTM woofers sum to 4 ohms
The easiest way to wire this would be simply to connect it in line with the speaker input wires from the amplifier.

Hello! I have a pair of ADS L400 (6.5" woofer) speakers recently matched to subwoofer. I want to buy a high pass filter. ADS were rated 48-20,000Hz+-3db 6ohm nominal/4ohm minimum. Should I get 80 or 100Hz and 8 or 4 ohm high pass filter? Thanks!
I cannot say which frequency will work best. Usually the lower the crossover point the better. I would recommend using a 4 ohm filter for that application.

Question about pass filters in general.
Having a hard time figuring out what these are for exactly. can these, or any of the other high and low passes, be used to crossover the dayton reference 8" 4 ohm woofer, and the dayton reference aluminum dome tweeter?
This is a passive high pass filter. If you add this to a full range speaker it would filter out bass. It applies a 2nd order (12 db/octave) slope at 80 Hz with a driver that has a 4 ohm impedance. You should keep in mind that any filter gets added to the existing acoustic response of the driver. The final result is a combination of the two.A crossover for your woofer and tweeter should include a high pass on the tweeter and a low pass on the woofer, and the filters would be closer to 2k and 80 Hz!
