The QM 215.61Q should fit fine. The woofers in the e46 are 5.25, the mids are 2.5 and the tweeters are 1 inch. The 'subs' in the HK system are 6x9. I don't think anyone makes 2.5 inch mids- at least I haven't found any in my limited search of the 'name' manufacturers like Kicker, Sony, JVC, Nakamichi, Rockford-Fosgate, MB Quart, etc. so you'll either have to keep them in, take them out and leave nothing in the holes, or unplug them. Good luck, and please post what you end up doing here. I plan on putting the Nakamichi MB-100 6-disc CD deck (with a mounting kit, of course) up front, a Nakamichi amp, and either Nakamichi, MB quart, or Rockford speakers (later on). Happy hunting!
