Bavsound is the go-to for aftermarket BMW audio upgrades.

I have a 2020 40i with the basic system. Looked at the bavsound options, speakers delivered and sent back. Found an installer in my area who handles higher end installations. Facial makes speakers just for BMWs. I have Focals at home, their products are always a step up from the ordinary. The Z4 basic and HK amps are built into the headunits annd are not separate. The subwoofer and rear speakers need access thru the roof compartment, too. I replaced the front 3 with professional installation(I watched it done). Not as simple or as easy as the bavsound videos look. Sound was transformed, even without a new subwoofer. I can add an amp with equilibration at a later time, but this was very cost effective. Remember, these are convertibles with loud exhausts, too. Highly recommended and worth slightly higher cost and effort

I had Focals installed all around in my 135i Cabrio and will do the same for my 40i too at some point. Love the brand and I think they've got a leg up on the H/K products.

I’m 99% the subwoofers are under the seats. Also, confirmed the main difference is 2 extra tweeters plus the upgraded amp. Page 42 here:

You may be right but I looked under the seats this afternoon and found nothing but carpeting. I believe the woofer (one on each side) is the larger, lower speaker in this photo of the rear panel.

Ha. So apparently “under seats” means behind the seats.

Here's my set up:
Audison has plug and play sound systems for our cars and that's what I went with. The OEM amplifier is still in the car. I can never go back to the OEM base sound system after this upgrade. Amplifier: AP F8.9 Bit Processor DIGITAL REMOTE CONTROL: Audison DRC Door Component Speakers: BMW K4E Rear Co-Axial Speakers: BMW X4E Subwoofers: APBMW SB-2 Center Console: Center K4M Plug&Play T-Harness: APBMW REAMP 2 |

I noticed their location the first week I took ownership of my car and was tweaking the sound system's settings. I make sure that whenever I place anything in that net storage area behind the seats that I don't block any speakers and only use that area for small objects like Totes umbrellas, baseball caps, etc.

I'm on the base system. The car looks stock as the speakers and subwoofers is a direct plug in to existing ones. The amplifier is installed just beside OEM amplifier. |

I'm in Bangkok so I found a shop who installs a lot of Audison systems. They are one of the top 2 car audio shops in Bangkok. https://www.facebook.com/MirageHiend...26452040215918 Another important thing is that they have installed for another Z4 G29 from their social media posts so I get peace of mind from the fact that they have done it before. I don't want to be the guinea pig car where they can mess up or damage the car during installation. I also got them to install sound deadening mat around the rear panels where the subwoofers are because it rattles from certain bass frequencies at a high volume. They also tuned the sound to my preference. I'm very happy with the sound system - big, big difference in terms of the clarity, staging (I tuned it in a way so it sounds the same from both the driver and passenger side) and the beefier bass from a more powerful amplifier. |
