I was hoping some of you guys could help me, I have the HiFi system in my M3 Cabrio and not the HarmanKArdon. I asked if it would be upgraded to the HK and they said it was practically impossible.
I really wanna upgrade my system and am not sure how to do it. What size speakers do I need? Which are the best for the M3? Where would I have enough space to place a Woofer and amplifier without taking all my bootsapce.
Also, anyone know what the difference is between the Business and Professional radio, I have the Sat+TV but with business and tape and I really wanna change it to Prfessinal and MD but have also been told that it is impossible....

Any guidance would be greatly appreciated....
