okay I am confused !! I read your deal about the CCC to CIC really want to do that soon !!!

BUT the audio deal has me confused we have premium sound but no EQ and no speakers in the "D" pillars
the AMP is VERY SMALL ... not like what is shown on REAL OEM as the TOP HIFI
we have subs one under each seat I believe

seems like the CCC to CIC is a separate upgrade and easier to do ...

is the BIGGER 650W amp PNP at all ?? I mean to say will the harness plug in ... ? can you get a separate audio harness ?
I did a complete MKIV NAV upgrade in a NON NAV car to a e39 540 so I have done something similar. I got an upgrade harness from BMW ...

anything like this available ... ?
