check the fuse box underneath your dash...(if your beemer has one under there) thats usually where the interior fuses are.

its a fuse but use a vm to check if any voltage is on the yellow wire n check fusebox nd replace any thats burnt n check for proper grounding also
amp should be fine it turns on when connected to a deck thats on and dissconect the battery next time

i dont know why you just wouldnt go get it installed by someone who knows what there doing...most places will do it for 50$ but instead now you have to pay for everything that you have blown up...i just hope you dident blow the deck..
