I have 4 ohm speakers in my car and they rattle and pop and sound terrible. Is factory 10 ohm? I don’t have the u66 code and I have concert 2 sound. Should I replace them with 10 ohm ones? I’m talking about the rear 4x10’s. The fronts all sound perfect.

I've never heard of 10 ohm. I've mostly heard of 4, 6 & 8 ohm, even some rare instance of 2 ohm.

Doesn't mean that 10 ohm doesn't exist.

Typically crackle & pop is loose connections, dirty potentiometer, or dried out & blown cones.

If you have a stock radio - stock AC Delco rear speakers are rated at 10 ohms. Improper impedance matching can lead to excessive power use, distortion, and noise problems.

Learned something new. Any idea why the 10 ohm rating?
