So i will give now the photo and information of the build
For the box of the speaker i have found a guy that gave it to me for free.
As for the speakers I have chosen
Subwoofer : Dayton audio epique E180He-44(does 4+4 mean 8ohm?)
Midrange: Markaudio maop 11
Tweeter : Skar audio VX4-ST super tweeter 4 ohm ( I wanted to buy from kleinanzeigen a scan speak 2905 tweeter but it is sold)
For the amp i chosen Wondom jab5 4×100W
And a battery board that need to be change because it can not supply enought amps to the amp board
And i want to build the crossover myself so i can learn something new and useful

PDF from amp board and battery board
I am open to design changes since I think that I have made a lot of mistakes

it can be wired either 2ohm or 8 ohm ( parallel or series of the two voice coils ).(does 4+4 mean 8ohm?)
Since your amp has DSP , no need for crossovers !, You have only one amp 4 ch ?. if yes, you'll need one more for the tweeters, a 2ch amp.
You may try this one! opps... opposite of 1.8mH the cap value is 3.3uF 🙂
note: use all cap min 100V, 2.2/3.3/4.7 are quite reasonable price but 15/33 may be quite a bit expensive but you may use two electrolytic capacitor in serise in this manner ---| (---) |---- [33 + 33 uf = 16.5 uf]

I was thinking when I design the crossover that the subwoofer works till 1500 hz and then the midrange starts from 1500hz till 10k hz and from there takes the tweeter
Does your crossover also has the value that I want?You may try this one! opps... opposite of 1.8mH the cap value is 3.3uF 🙂

Maybe it's better to put the work In the passive filters for the Maop 11 and the Skar tweeter. Since there are 2 amplifiers per channel, the crossover frequency can be kept rather low (200-300 Hz?) ...You have only one amp 4 ch ?. if yes, you'll need one more for the tweeters, a 2ch amp.
I dunno, the dual voice coil suggests to use all the 4 channels for the woofers!!!
I see that my amp board has adau1701 dsp and a program called sigma studio.
Can I install crossovers and then do fine tuning in the program?

You mean that I should connect al the 8 cables to the subwoofer since the amp board can 4 ch 100w , 3 ch 1×200w 2×100w or 2 ch 2×200wMaybe it's better to put the work In the passive filters for the Maop 11 and the Skar tweeter.

I don't know your attitude towards this build. If it needs batteries, then it's gotta be mobile or... private grid!!
So, if mobile and less power hungry, try 2 channels splitted woofer( series connected) and midwoofer+twetter passive crossed.
Or the power subwoofer system that uses 2 more amplifiers for the midwoofer and tweeter.
