Duel 4ohm sub multimeter ohm check
I have a boss audio system 10” 850 W duel 4ohm sub. When I hooked up the multimeter to check the ohms it’s reading 6.2. I was under the impression that the on reading should be around 4.0 Is that a bad sub? Or blown sub? Also when I smell the speaker it’s not like burnt wiring. Burnt voice coils? When I press down on the sub it will jump from 6.2 up to 13.3, 27.2 And everywhere in between. But it always settle at 6.2. Am I supposed to have that much variance?
