3-Series (F30) and 4-Series (F32) Sound Systems

The speaker systems in the F30 and F32 models are available in 3 different specification levels:

Base/ Basic Audio

This is the lowest-level BMW sound system, unavailable in the US and Canada. It consists of 6 speakers (4x Midrange, 2x Underseat Subwoofers) which are powered by the iDrive head unit with no additional BMW amplifier.

HiFi Sound Systems

This is an option one level above the Base system. This consists of 9 speakers and a seven-channel amplifier integrated into the loudspeaker system. The amplifier has no MOST bus connection and instead receives the switch-on signal via a separate line. Seperate speakers are installed in the HiFi system for the treble and mid-tone ranges. The HiFi system also has a mid-range speaker positioned as a centre speaker.

Top HiFi (Harman Kardon) and 'MOST' Sound Systems

This is the top tier BMW sound system. It consists of 16 speakers in total, with a 9-channel amplifier incorporated into the Sound system. The AMP is a bus connection in Media Orientated System Transport (MOST)

Speaker panels labelled with the 'Harman Kardon' lettering, a tale-tale sign of a Top HiFi (MOST) system

Important Fascia Notes

• The fascias are made to suit industry standard sized stereos such as Pioneer, Kenwood, Sony, Alpine, JVC etc, NOT INCLUDING China units or unbranded units. 
• China units have a reputation to be over sized and may require modification to the fascia to allow it to fit.
• We do not take any responsibility for China units not fitting as they are not industry standard size.

Car Audio Fitting Accessories are sold with limited instructions. Some knowledge of car audio installation is helpful, as in some rare case "modification" is necessary.

Please make sure that is the correct Fitting Kit for your vehicle by firstly checking to see if your vehicle make, model and year is listed in the description. Secondly by checking to see if the connection & Shape in the picture listed is the same as you have in your vehicle. If in doubt please email us with your vehicle details and we will confirm what you require.
