This thread was a godsend.
Thank you.

Just finished upgrading my 2008 E90 M3's Logic7 sound system to the Dirac individual audio system.
I can confirm that this works even if you don't have iDrive with one caviat. It seems I lost the ability to enable any kind of surround sound mode, I do have the choice of Music and Cinema modes on the OEM head unit but they have no effect.

Regardless of this, the sound seems better/fuller than the Logic7 system as far as I can tell. I only just tested it for 10 minutes.

Also, the OP is correct. The AMP worked with the original VO $677 just as well as $752. There were no audible differences or functional differences I was able to dicern.

Happy to hear mate.

I just did the (almost) the same thing with my M2 converting shit Harmon Kardon (rebadged Hifi 676 option) to the Bang & Olufsen taken from an F13 M6 and it sounds incredible

I found that between the L7 system and the Dirac system, the improvement is marginal, but what I was really hoping for didn't happen.
I was looking to improve in the mid-bass area which I found severely lacking on the L7. Seems the Dirac system does not resolve the issue (as I initially thought).
My guess is, the use of the small door speakers limits this frequency range from being reproducible.

I'm talking about the 100-250Hz range. Feels empty.
My 2003 GLI beater with Monsoon system sounds way better in that respect.

Oh my this is such an excellent DIY reisf !Just found a used L7 amp, cant wait to try this guide. Before i attempt to scout for more parts, can anyone share a Trace file from CIC Nav Pro with Logic7 optioned? Just want to compare parameters when I code it with NCS. Thanks guys

Hello to all sound lovers
I installed all the speakers, crossovers and amplifier in my BMW E63 (CCC). How do I code the S752A option instead of the S677A and how do I code the amplifier (65127841379) for my E63? Maybe there is a step-by-step instruction?

Nice guide, just retrofitted my Logic7 too!

Just one question about power supply to the amplifier - is it ok to power it from battery? Since it will be always "ON". If you power it from the glove compartment fuse box it will cut power after 30min when car goes to sleep. So I am wondering does it draw power if you power it from the battery like in your guide?
