Post by OK51MON » Tue Mar 06, 2018 8:18 am

I have a rainbow setup in my other e8X car and its so much better.

Can anyone advise on the best way to upgrade my sound system in my 2012 F20

My option list is 674 Hifi Loudspeaker System Harman Kardon.

Can anyone point me in the right direction.

Had anyone else upgraded FROM this system to an aftermarket

Focal do some nice speaker kits for BMWs it’s called the plug & play range and it pretty much is swap for your speakers. I would go to car audio place and speak to them. I’m not sure how good the amp is in the HK setup but speakers are the most important...
