Good day, community.
At first place i would like to apologise if there is a similar thread, but search button doesn't work for me. After googling a whole day, im not quite sure if i understood ir right. I hope that anyone could help me.
I would like to make a 3-way speaker with all 3 drivers being 8 ohm individual.
I have not best but decent amp from my car setup. 2x150w rms@2 ohms or 2x75w rms@4 ohms.
If i would connect my desired drivers in parallel direct to amp it would require 2.66 ohms amplifier. In this scenario ohm ratio is tolerate.
If i connect all 3 drivers to 3-way crossover designed for 8 ohm drivers will it require 8 ohm amp output or 2 ohm amp is just fine?
8 ohm lows + 8 ohms mids + 8 ohms highs + 8 ohms XO = ???
P. S. I dont seek to burn my house or amp

When you use a passive crossover inside the speaker, the amplifier sees 8 ohms at the frequencies
in each driver's range, but much higher ohms outside that range. Then the three ranges combine
in parallel to provide 8 ohms in the entire speaker's range. So you'll have an 8 ohm speaker system.

With this, you can use 4 ohms or 8 ohms. Don't use 2 ohms for this configuration.
4 ohms will give you a little more power, but it is not much.. you almost won't notice the difference.
Thank you for answer! Just to make sure i understood it correct. If i would connect 2 x 8 ohms crossovers in parallel on one channel would it make a total of 4 ohms load?
i assume my question offended you. Could you explain it please so i could understand what is so wrong about my idea?
Probably I don't read carefully...probably the title drove me nuts! As there's no 2Ω amp or whatsoever. But, yes, you can parallel 2*8Ω crossovers ( whatever that means) and make it Z=4Ω.Bearing in mind that those numbers are ...uhm...er,,,( I'm losing the memory)
Symbolic or, they do represent a Segment, well something starting with the letter S

Well my amp is realy 300W x 2-Ch @ 2-Ohms.

I have no idea - yes, the halving of output is theoretically right, going with double Z load.
You have to chose the specific drivers - woofer, midrange- tweeter and make a crossover tailored to them. Or find a specific design with drivers and crossovers already tested. Nothing particular difficult ( the latter )

Looks like 4 ohms at bass and treble, but 2 ohms in the midrange. Midrange will be louder.Any thoughts about this setup below?
one XO would produce 8 ohms impedance, in my scenario i would lose some power.
A 4 ohm crossover does not make the speaker 4 ohms. Instead it is called a 4 ohm crossover because it is designed to adjust frequencies better with 4 ohm drivers, that is all.
You have this for left and again for right. Dont add them together, you use a separate amp for each side so work them out by themselves.
At each of bass and treble frequencies you have one driver, the tweeter is 4 ohms and the woofer is 4 ohms. At midrange frerquencies you have 2 drivers, both 4 ohms=2 ohms total.
