The BMW “HiFi” system

The BMW HiFi sound system looks good on paper, but it doesn’t sound very good – and it certainly doesn’t qualify to be called “high performance”. It sounds harsh, dull, and weak – high in distortion, low in power. Here’s what it includes:

– Front tweeters
– Front midranges
– Underseat woofers
– Rear midranges
– Rear tweeters (2006-2009 vehicles)
– Six-channel amplifier with front/rear/woofer outputs

The amplifier also has some rudimentary sound processing in it, to make the HiFi speakers sound less annoying than they otherwise would. Fortunately, the balanced signal from the stock head unit to the amplifier is unprocessed.

Musicar Certified sound systems upgrade the most important speakers, as well as the amplification. The stock head unit is retained and all functions work just as before. All the new gear is plug-in and bolt-on. The installation is 100% removable and reversible.

Musicar systems for the E90 with HiFi are available in three levels of performance. Each has the following optional configurations:

– Rear-speaker delete
– Stock rear speakers retained
– Rear speakers upgraded

Each of the above can be ordered in a four-way architecture, with our OE-Look trunk subwoofer enclosure loaded with the appropriate woofer. In each of these systems, the underseat woofers are band-pass filtered and driven as dedicated midbass speakers. If you select a system with the trunk subwoofer, please advise us if your E90 is pre-2010 and has Sirius Satellite radio installed, thanks.

So while the chart might look imposing at first glance, we think you’ll decipher it fairly quickly. For a complete hardware list, please contact us via e-mail, thanks.

Our favorite systems, and the audiophile’s choice, are the “rear-speaker delete” packages. (We’ve been saying for years that rear speakers are a Commie plot.) However, if your car has Rear PDC parking sensors, we recommend rear-speaker retention so that the directional audible alert is also retained. If you listen to 95% rap and hip-hop, or techno and electronica, you may want to upgrade your rear speakers, since these genres do not benefit from the traditional stereo “front-stage” effect.

The majority of our clients order systems without the trunk subwoofer. Truly startling performance is possible without it – most people haven’t ever heard a system with two 8-inch woofers buried in the floor.

If you order a trunk-sub system, we limit how low into the bass region the underseat woofers play, and reserve these notes for the trunk subwoofer, which can play them with much less strain. This results in a four-way system – tweeter, midrange, mid-bass, and subwoofer – which many feel is the highest-performance system architecture there is.
