Mein Auto: 05 Bmw 645ci convertible
Im having the same problem on my 05 645. The left rear sub makes a pop noise when i turn the car on then when i turn the volume up it makes a crackling noise as if it was blown, So i went and bought 2 07 m6 subs from a junk yard and hooked it up and still the same. So i took the left rear liner off inside my trunk (couple of torx screws and clips)removed the amp and it looks like it was replaced already cause there was paint on it saying it was 04 645. It also had dried condensation marks, im gona try replacing it too because i heard this amps go alot on these cars because of the condensation from the amp being so close to the drains, hopefully it'll take care of my problem...:/
