BMW G series i4 / i5 options

The new G series cars brought along new electric platforms and with them, slightly different speaker layouts. Unlike most BMW, the i4 and i5 have the front mid bass speaker in the door, rather than under the seat and it is limited to a 6.5" speaker in all audio versions. While this has a negative effect on the bass response, having the mid bass speaker in front of you can improve the front sound stage.

​

Like all G series cars though, we now have the MGU (Media Graphics Units) and RAM (Receiver Audio Module) which is located in the boot. The RAM is essentially the kind of amplifier which would have been inside the old style head units, IE still very low power.

 

Base Audio - No tweeters, 4" in the front door, 6.5" mid bass in the front door, 4" in the rear door, high resistance speakers

Hi-Fi - Tweeters in the front doors with non branded grills, 4" in the front door, a centre speaker with tweeter, 6.5" mid bass in the front door, 4" in the rear door. Low resistance speakers

Harmon Kardon - separate booster amp for the front mid bass and sub, metal dome tweeters with branded grills, 4" in the front door, a centre speaker with tweeter, 6.5" mid bass in the front door, 4" in the rear door with tweeter, surround speakers, 8" sub enclosure under the floor in the boot

 

While the Harman Kardon in these cars isn't 'bad' for a factory system, there is still a huge amount to be gained dynamically and tonally in adding a DSP amp, replacing the cheap factory speakers and adding a dedicated sub to give real sub bass.

​

Because the Harmon Kardon set up in these cars is different we have given it its own sound package. If in doubt, please feel free to give us a call.
