Car speakers and creating a crossover

[Stingray5funk]

Hey everyone! I’m wanting to swap my speakers out in my car with some Dayton audios

I have currently swapped out focals for JBL GTO components as one had a blown tweeter anyways

I’m running a PPi 900.4

Channels	4 ch. Class D
RMS Power 4Ω	145 x 4
RMS Power 2Ω	225 x 4
RMS Power 4Ω Bridged	450 x 2

and I run deck power for my rear speakers which is 50 watts peak

I’d like to get some Dayton audios and a tweeter problem is
I need a passive crossover, I understand by using DSP I’ll get better fidelity but I also am using my rear bridged Channals of the amp to bridge for a sub

So I’m limited on inputs and outputs and want to stay passive

Can anyone help me with designing a passive crossover ? Or teach me and explain how I can create a butterworth filter (at least I believe what it is)

Not once you gain the experience to get the same either way.

Until then you might start by learning to tweak. Your drivers and their acoustic position are not even to begin with. Simple formula based calculations will only get you so close.
