After a few weeks of listening to my new X3 E83, I've noticed that the passanger side speakers need some work... therefore, I'd like to replace both door speakers with something better than the OEM. I've viewed the BAVSound videos... but I'm not sure which speakers to go with. Do I need sound deadening material?? I'm not an audiophile snob, but a significant enhancement on OEM would be ideal (especially to reduce the "rattle" at modest levels).
Thanks.
