I need to choose the right crossover

[cometa_gam]

Hello, I want to buy a pair of Dali Oberon 1 woofers with tweeters on eBay, but they do not come with a crossover. I plan to install these in the doors of my car. I also have a single 3-inch midrange speaker. Could you please help me decide which crossover I should buy to ensure all the speakers produce good sound?

amplifier i using (Fosi audio v3)

I see that Amazon sells 3-way crossovers, 2-way crossovers, and 1-way midrange crossovers. Which one would be the best option for my setup? Thank you!

It’s not April 1st until next year!

I recommend car speakers for cars. You need to choose the right product to begin with. Welcome to the WHF forum.

My recommendation is to learn to respect enthusiasts, answer specific questions, or skip!!

Which is why nopiano said use dedicated car speakers, as Hi-Fi speakers are totally unsuitable for a car environment.

Crossovers need to be tailored to the specific drive units in question - an off the peg solution might work in terms of sound coming out of them, but is extremely unlikely to give as good as they are capable of - by a long way.

Most woofers in a two-way loudspeaker will be crossing over between 2kHz and 3kHz (sometimes a little lower or higher), but that is governed by the woofer's capabilities, and the capabilities of the HF unit it is integrating with in the correct size box. A loudspeaker is a set of compromises that are balanced to produce the best sounding option possible, or to achieve a certain goal.

The April 1st comment was both unnecessary and unwelcoming in my view, though...

The whole point, I felt, is was absolutely nothing to do with the hifi section of this forum in which it was posted. In fact nothing to do with hifi at all.
Also April 1st might have no meaning whatsoever if the OP is from abroad.
As @nopiano states trying to incorporate hifi kit into a car is really a no-go area, he's better off spending his money on automotive gear specifically designed for such a job.

The OP also mentions using a Fosi Audio v3 amplifier, a domestic mini-amp designed to run off a mains power supply. Another quite unsuitable product for a car environment.

I really think it’s a trick question for a first post. In effect: “I’m trying to fit Hifi speakers into a car, they don’t have a crossover for some reason, and I’m planning on using a home amplifier from a 12v battery”.

I want to know where the turntable is going? Happy Christmas! 🤣🤪🎅🏼😤

Fosi amps use external power supplies do they not?

and a quick glance of a picture of the back panel shows they run on 24-48v DC....

try getting that from a 12volt battery.
The OP clearly doesn't have any idea of the issues he is facing, unfortunately posting on this forum is unlikely to get him any further I feel as nobody yet has even attempted to tell him how to do it....

They sure do. I have one hence I thought I should point out its unsuitability.

How do you imagine that it might work in a car?

DC to DC converters are cheap and readily available...

Oh dear....

But there’s nothing to attach it with, it would probably shake to pieces, and it would overheat in a confined space. It’s totally unsuitable. So are scavenged Hifi speakers. Quite unsuited for a car, not rugged enough, not damp resistant, insufficient space to load or mount them.
