It's a costly mistake not to have ordered the HK system. Penny wise pound foolish. I made a similar mistake with my GTI and had to spend a fortune to get decent sound. Aftermarket systems that provide a similar and/or higher standard of sound to a factory premium system will cost much more. Labour charges are the killer in the UK.
The standard system in F30 is pants. The problem is amplifier distortion which keeps clipping at higher volume levels and the rubbish loudspeakers with overheating voice coils adding even more distortion. Both these components need changing. Remember the adage: garbage in, garbage out and then double garbage out as the loudspeakers simply cannot provide the frequency range or dynamic range.
Quite often, factory fitted options, especially with audio systems, are the most economical route to nirvana.
