If I had my time back I'd NOT replace the 6" speakers as I feel the BMW ones offer a bit better OR even same sound response as the JL's and It took me a few hours to remove speaker, remove speaker physically from its plastic basket perfectly, clean basket, silicone install new JL speakers, let them cure and reinstall. Not worth it to me. The sound increase from the other two speakers (tweeters and mid range) are MUCH more impressive (and way cheaper).
