Hi All,

I'm under delusion and need someone to talk me out of retrofitting BMW Individual Audio to my base stereo system (6 speaker). Here's what I think I'll need:

- A Stereo Harness (4/6 from Technic?, maybe a stock one if it can be sourced?)
- BIA Amp (825 Watt Lear one)
- 16 speakers
- Dashboard center speaker grill
- Parcel Shelf with speaker cut outs. (For E92 I think it's just two cutouts for 2 'combo' speakers)
- Rear door cards with speaker cutouts for midrange and tweeter.
- Speaker grills

- Recoding to HIFI/ BIA
- taking out seats to fit in subwoofers


To me this sounds like a fairly involved plug in play, but I can't be the first person to have considered this, and thus I'm a little worried that it's going to be a bit more involved than just splicing wires, new terminals, MOST connectors and other unforeseen items. I'm hoping it's not way outside the realm of a casual DIYer...

I wouldn't say this was simple in any sense.
Yes you could do it and people in Europe do but you could do better going aftermarket.
Usually they find a donor car or complete wire harness and hardware set.
Technic's stuff is really not set up to do this.
You don't have to remove the seats to change the speakers under neath the seats.
Just lean them back and remove the Pod's there contained in .

Basically the same as Logic 7 with the exception of the amp wiring .

There used to be some big guides on doing this can't find them now.

the harness you need is genuine logic7/individual audio, not technic
the rear trims is easier to cut with dremel then search another with cuts
because you already have cut for mid speaker
the rear shelf has to be swapped, thats correct

I've sourced a donor car, and now I'm having second thoughts after sourcing the stuff.. will document this page as I proceed ��

If you lean the seats back, will it trigger an airbag warning?

I have the Harman Kardon, can I just swap the speakers and AMP os is there any wiring?

Could BMW or a mechanic code in the new amp?

As long as you don't unplug the seats it will not trigger any kind of alarm.
And there is plenty of cable to do that. Pictures included in link

If you are going to work on the car for a long time you may want to
disconnect the battery so it won't get drained.

yes, you can, but sometimes individual amp may want more power and then direct wire to battery is used
