I have recently purchased a 2009 335i convertible and the sound system is pretty underwhelming. What are the recommendations out there for speakers/amp that is compatible with the original head unit? Thank you

first be sure of which sound system you have in a 2009 US car that would be
676 Hi Fi or 677 top hi fi . The first one is easy to modify the second one 677 is not because of the fiberoptic input and the 9 channel amp. Use mdecoder.com to list your factory configuration. This means amp and speakers the head unit is a different set of problems. Hi Fi 676 stereo system is simple analog input and output.(easy to modify ) Top Hi FI aka Logic 7 aka HK is hard and or expensive to modify because of Fiber optic Input from head unit and 9 channel amp . There is one company that make a drop in amp for this called Mobridge I have seen no others . Reprogramming of head unit to analog is possible but requires the right software and hacking.

If you have a convertible be sure to check all the seals and drains.
