How many ohms is the factory subwoofer in a 2014 Mercedes e550 with Harmon kardon ?

its a powered subwoofer assembly with fiber optic signal input.

doesn’t really justify if it’s a 4ohm or 2ohm subwoofer

My understanding is it's 2 ohms, I wanted to update mine a few years ago and the stereo store guy said "oh that's two ohms"

okay perfect. I’m gonna tap in my jl audio 12w6v3 to replace the oem woofer

Let me know how it works out Devon, please. I still haven't done mine and have always been upset that my '13 sounds way better than my '12, I just never got to it. Both have the HK sound, so I have never been able to figure out why one sounds so much better.
