5 kHz High Pass 4 Ohm Crossover
I have an amp that can use 4 or 8 ohm speakers, I have a Full range speaker @ 4 ohms and tweeter @ 4 ohms, if I wire them in series with this cross over inmbetween should I use a cross over that is 8 ohm (since there wired in series 4+4=8 ohms) or 4 ohms.
Unfortunately you cannot properly wire a full range and tweeter together in series with a filter in between, it will filter both drivers. Your best bet is to use a 2-way crossover, or simply run the full range without a filter and wire the two together. You will still end up with a 4 ohm overall load.

If I wanted to make this Xover at 2,500 instead of 5,000 what size Capacitor would I need to replace it with.
You would need to replace both components, not just the capacitor. They would need to be replaced with an 11-12 uF cap and .35 mH coil for a crossover at 2,500 Hz at 4 ohms.

I want to run 4 8ohm tweeters (2 in each A pilar of a car). I will be wiring each side in parallel for 4 ohm load. My question is can I run one of these on each side inline with the tweeters? Tweeters wired parallel prior to the crossover
Yes you can use one of these per pair of tweeters in parallel.

This vs Capacitor
What is the advantage of using this vs a simple 8µf capacitor?
A capacitor will only provide a 6dB per octave roll off which is not much protection. To compensate for this, the crossover point must be much higher. This high pass filter uses a 12dB per octave slope which provides better protection for the driver and also means it can be crossed lower.

I see it says 4 ohms. What does that mean? The woofer must be 4 ohms? The tweeter must be 4 ohms? What if I used a Dayton classic 5.25 size 4 ohm and an 8 ohm tweeter? I have not ordered this yet. It would be an extra pair as I have two Dayton classic 5.25s ( The 19 dollar ones) Then I can order a tweeter of around 16 bucks price or less. I just want a small inexpensive pair as i have several larger speakers. I like to experiment. This is a low cost project.
This crossover is deisgned to be used with 4 ohm drivers. Being a high pass at 5kHz it is only designed to be used with tweeters or high frequency drivers that are 4 ohm.

Does this crossover have to to be broken in?
I have this crossover on a 4 ohm Phenolic Ring tweeter, and it produces an obnoxious clipping noise when I turn up the volume. Will breaking them in eventually get rid of the clipping?
No. You never need to break in passive electronic components like capacitors or inductors or resistors, just like you don't break in your iPod before initial use. Speakers are different as their mechanical compliance changes slightly.
