Hi Stephen

Welcome to the Forum

I thought there was an Amp in the back (could be wrong and imagining stuff) 

If you are not aware there is an online BMW parts list www.realoem.com, put the last 7 digits of your Vin into the search box it will bring up your model. Then search the relevant section there will be small exploded drawings of each component and indications of where they fit.

Obvious stuff checked? No plugs loose fuses blown? 

Good Luck

Dave
