FS: OEM 2016 M4 Harmon Kardon Underseat Subwoofers

BIMMERPOST / Classifieds
Asking Price:
Sold

Item Interest
Selling OEM Harmon Kardon Underseat Subwoofers from my 2016 m4. The car has under 2,000 miles on it. Got the Bavsound as a gift. Let me know if pictures are needed, but the subs are in perfect condition. I had no issues with them and would not have replaced them, if I did not get the Bavsound as a gift.

Edit: these are the OEM woofers, I misunderstood. Good luck with your sale!

Will these work with the HiFi system? I have HiFi system but upgraded to Bimmertech Amp and Bavsound Stage 1 speakers. Wondering if these are plug-n-play and can replace the HiFi stock woofers.

I believe the impedance between the HiFi and HK speakers is different (higher on the HK) so they should work with your setup at a slightly lower max volume level.

These should work with your HIFI sound system and will definitely sound better than HIFI subwoofers. Reason I am so confident is because my friend just got a 428i gran coupe with HIFI system. The bass was a lot worse than my M4. We both upgraded to the bavsound Underseat subwoofers, and installed same time. The speakers were identical and both were plug and play. So i do not see a reason why the Harmon Kardon subwoofers would not plug and play in to the HIFI sound system.

I actually figured that the people that would be most interested in these subwoofers, would be the ones with a HIFI sound system.
