Sub woofer

BMW subwoofer install?
Please can anyone advise/ help me.
I would like to install a small subwoofer in my 2016 F21 120i.
Can anyone advise if this is possible with the standard NBT head unit?
We’ve upgraded the fronts & rears to Harman Kardon already but just need a bit of bass.
Or should I install the Harman Kardon subs under the front seats, again any help/ advise with that would be greatly appreciated.
Is this plug and play?
Many thanks Glen.

Hey there, have you changed the amplifier to the Harman Kardon one or at all?

I have the Harmon Kardon Sound system and it is amazing quality. I have since upgraded the amplifier to the Match Up 7BMW DSP Amp which is fully customisable and also installed a sleek sub in the boot. The car sounds incredible.

If you get an amp with high level inputs, you can tap into the underseat speaker wiring and use that to send signal to amplifier.

I'd recommend a mini amp as they are easy to hide behind trim panels in the boot. I use a Kicker Key 500.1 and it does the job well, but I'm in a country with limited brands.

I have Focal underseats running off a Kicker Key 200.4 amp and they add a bit of bass but not enough to justify the upgrade cost. Far better to go the subwoofer in the boot.

As a comparison, wifey's car (F10 530d) has the HK system and I find it completely underwhelming.
