I have a BMW e90 325i, how do I know which type of system I have? Such as base/stereo, hifi, L7 etc

If you have a center speaker you have logic 7.

If you don't have a center speaker on the dash, but you have tweeters, you have hifi.

If you have neither, you have base.

If you have the center speaker (on your dash), you have Logic7, tweeters for HiFi if you have none, base system.

Okay noob question what are tweeters?

Simple answer, they're just another type of speaker.

If you have them, they should be on your door, towards the windshield (where your side mirrors are but inside)

Are Logic 7 and H/K two different systems? The reason that I asked this is because I have a center speaker and an L7 surround option on Idrive menu as well as H/K tweeters.
