I'd like to get some opinions on what I should do with a 3-way Harmon Kardon speaker set-up that I pulled out of my old 02 Range Rover... Here's what I have: Two 1" tweeters and two 3" mids. This setup also had two 6.5" drivers but were blown when I pulled them out. The tweeters appear to have an in-line filter but I haven't cut back the heat shrink yet to see for sure. The mids have no filter. Anyway I was thinking of maybe building a set of shelf speakers but I don't know what I should do about a crossover. All speakers are 4ohm and I would like to keep this a 3-way setup so I will have to get new woofers. Also if anybody can tell me what the power rating may be for these things I would appreciate it. Thanks in advance.

I suggest selling them on Ebay and buying a set of speakers for your home.

I went ahead and took a look at the filter... It reads: Bennic 6.3 MFD 50WV NP. Can anyone tell me what this means?

It is a 6.5 Microfarad capacitor. The 50 wv is 50 Working Volts. NP is Non-Polarized. There is a chart somewhere on this site that will tell you the crossover frequency of a 6.5 mic cap into a 4 ohm load.

Very near 6000Hz https://www.the12volt.com/caraudio/cross4ohm.asp

Can anyone suggest a way for me to make my own crossovers for this setup?

Figure out what frequenies you want to cross the mid at, I would suggest 6K as the low pass, and 250 for the high pass. For the mid of course. Look at the top link for a diagram to connect the cap and the coil. The second link will give you cap and coil values.

Okay... one last question. Do I wire the three speakers in parallel with each other as well as the appropriate capacitor and/or resistor and if I do does this still give me a four ohm load??

Yes they are all to be wired in parallel, If the crossovers are designed properly, the impedance will be 4 ohms throughout the full audio specturm.
