Please note that the E93 takes more installation time in the trunk than other E9x platforms. The doors and underseat installation is the same as an E92 coupe.
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 (early models only)
- 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 E93 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
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. We think everyone should get to hear a real high-performance audio system with 8-inch woofers in the floor.
German-made speakers, far higher clarity and low-end extension than stock, much less distortion.

We don’t use trunk subs in the E93, and we don’t have as many full-system options. We run out of hiding places for gear in the E93, and we won’t offer a system which compromises the utility of the trunk.
