Maybe since the system is stock up to the speakers, someone here knows how the OE radio and amp are set. I sure as hell don't.

I think they did- like the ones in the dash. We did not put it back on when we replaced with tweeters, but we did use it for the dash mids. They sound great.

Yes. I have heard that the DSP amp has a crossover and that there is no need to use the ones that come with some component sets. I think that was Jay who said that.

I have no freakin idea what this would sound like. Sorry.

Woohoo!! I am getting pretty good at this! I even looked at a Grom(?) thing. I have Bluetooth, but it's not terribly loud. I (now) like the idea of HDRadio. And it would be cool to navigate my streaming audio from the steering wheel.

We'll see how the next proactive stop in to the mechanic goes. Next month is 6 years for this X5! I'm getting close to having it longer than the 3.0!
