100 Hz Low Pass 4 Ohm Crossover
I have a Alpine 1043d sub from a car. I've made a 40L case and hooked it up to my Harman Kardon HK970. The subwoofer is connected to two rear chanels, both 4ohm. My front speakers are Jamo Studio 180 speakers. I think I need two of these, right? Thanks!
If you are hooking up one coil to each channel yes, you will need two.

What would the effect be if I would hook up an 8 Ohm subwoofer to this crossover. I accidentally purchased this unit instead of the 8 Ohm version.
Plugging a 4 ohm driver into a crossover meant for an 8 ohm load will cut the crossover frequency in half.

for a dvc (2+2ohm)...
if i combine both 2ohm coils on a sub to run a 4ohm load from amp, do i still need two of this, one for each coil, or can i use the 2ohm coils wired together/4ohm with a single one of these low pass filters?
If you wired the coils in series for a 4 ohm load you only need to use one low pass filter between the subwoofer and amplifier.

What are the physical dimensions of this item?
This crossover measures 4-3/4" long, 1-7/8" wide and 1-1/2" high at the highest point.

Will wiring a 4 ohm crossover to a 4 ohm speaker reduce overall ohm load to 2 ohms
No, crossovers are designed for specific loads, 4 ohm, 8ohm, 16ohm, etc... if designed correctly the impact on final impedance of the speaker should be minimal.Since the effect of the capacitive and inductive reactance depend on the load impedance different values of both capacitors and inductors must be used for speakers of different impedance values.To achieve the same crossover frequency on a 4 ohm load as an 8 ohm load you must half the inductance and double the capacitance. The opposite is true for a 16 ohm load vs. an 8 ohm load.

Two drivers using Hp & Lp ?
Building my first project speaker.I'm going to use a 15" Boston Acoustic subwoofer and a Goldwood GW-10PC-4 10".What i want to know is, if i'm using a 100hz Low pass Filter for the 15" and a 100Hz high pass filter for the 10", will my impedance will stay a 4ohm because i'm using filter ? Or it will drop a 2ohms ?Thanks
It will stay at 4 ohms but may drop to 3-3.5 around the crossover point. This is fairly typical, if you have an amplifier that handles a 4 ohm load this will not be a problem.
