Changing head unit + speakers...! (1 Viewer)

[WarTruck]

If I change the stock factory head unit out for an aftermarket one, how do I determine what the correct specs are for new aftermarket speakers, such as impedance, power, etc?

As I understand, when you stay with the factory head unit, you have to find aftermarket speakers that have the same impedance as the factory speakers. Do I still need to use that same impedance if I have an aftermarket head unit?

I'm not looking to run new wiring, etc. I just want to remove the old speakers and replace them with same-fitting aftermarket's.

Nothing to be concerned about, all head units are designed to work with 4-Ohm speakers.

Aside from component speakers, all car speakers will be 4-Ohms. Power ratings are ambiguous.
