Anyone upgrade their OEM sound system?

Appreciate it. And that will work for my entire system correct? I had a technic harness in my 335 HK system that plugged into my factory amp and let me run a pioneer amp and sub but I'm pretty sure it was only powering the sub

Correct, assuming you use a 6 channel amp then it will power all 6 speakers including the 2 subs under each seat. The 335 harness sounds different in that it allowed you to piggy back on another amp to the factory amp. The M3 technic harness is intended to allow a complete replacement of the stock amp instead.

Awesome thank you for all your help. I'll message technic and get one. Seems that everyone uses that same amp. Forget the model number, but any decent six channel will suffice?

Should work with any 6 channel amp. Everybody uses the JL audio xd600/6 because there aren't many other quality alternatives. 6 channel amps are rare. I have seen some refurbished JL amps online at a good discount if you're willing to take a chance.

Yeah that's the one haha. And I'll still be able to add a trunk sub to that with the harness correct?

The trunk sub I'm not sure about. Technic will know. Most guys seem happy with the 2 factory under seat subs once they are properly driven with a good amp. It's the front door speakers that seem to be the weakest link speaker wise in these cars.

Awesome. Thanks again for all the advice. Looks like that's the route I'll go. I'll try out the amp with technic harness first and think about doing the rest. I can just swap in eps speakers right? Without having to go the whole nine yards with the bavsound stage one upgrade?

The eps speakers will work and the reviews I've seen have been all very positive. I went a different route and picked up the Focal IFBMW-S (not installed yet). Not cheap but I heard them in another BMW (all other speakers were stock) and it sounded awesome. The Focals are plug and play but only fit the sedan.
