BMW e46 M3 budget build AV system

[NealfromNZ]

Have been lurking around the forum and are a general AV nut. Have an older AV rig , analogue hifi system from the 80s and I a dyi car stereo hobbyist.

The car concerned is a BMW M3 from the 2000s . Its a great car and mine has the circa 2002 factory AV package which has a 16:9 7.5 inch screen , TV tuner and a factory 10 channel hifi package.

A few years back I gave the audio and AV side a revamp with two goals. Budget speaker and amp based on end of line NOS and to put in a system that was still ok for track days and could be removed an returned to factory should I sell it.

System interface. Kodi media player controls mapped to BMW nav control buttons via system bus controller. This was an earlier interface I ran

Wow... very serious install there... love love love the subs behind the seat and the BMW emblems... very clean and cool looking.

I was going to do an install in my 2012 528i, but ended up selling it for a truck before I ever got around to it. It was going to be very similar to what you did with the subs behind the seat.

Very cool. Gives me ideas for my E46!

Thanks Sonnie , I spent a few years on weekends take the interior apart and then putting things back together for work day use.

Ive had a few car audio systems since the late 80s and with this one set a lower budget as a challenge and brought up end of line stock. On the BMW the ski pass installs for the sub give really clean bass compared to my other trunk installs.

All that is left to do is run through a session with REW as I’ve tuned time alignment by ear and the response curve is more home hifi than running a car curve. Ive had good feedback on the overall sound quality and most don’t believe that it’s run by a $40 raspberry pi.
