Hi I'm thinking about installing an empeg into a 2001 BMW 3 series. It has harman-Kardon, so the head unit isn't standard DIN size, so I understand that i would have to purchase a Conversion kit to do the install. my question is about the subwoofers that come with the factory system, because I understand that the EMPEG doesn't support sub-woofers. Is that true? Is anyone familiar with the 3 series to be able to comment on that, or any other complications that would arise on an install?

Also I am going to make the plunge this week at Carplayer to buy a Mk2a. I originally thought that it would make sense to buy the 10GB and then just do an upgrade later, but after reading the FAQ on riocar.org it seems like it's a fairly intense process for a common laymen. Has anyone done a drive upgrade with little technical background and would care to comment on the feasability?

Thanks this community is terrific & I can't wait to start playing with my new EMPEG
