I've got some trouble with my E46 2005 330D, my right hand side front speakers has stopped playing sound, so has the middle-size speaker in the left front door too..

As I can see in other forums and threads, it seems to be the BM 54 radio/amp module who's the problem. I can solder/resolder but I dont know which points to resolder.. Can I get any help??

Anyone know which points to resolder?

I've seen that it's possible to buy a repar-kit for BM54-modules, which is some kind of cable-kit who is supposed to be soldered onto specific points.. Is it possible to just resolder some points without buying the repair-kit?

very grateful for answers!
