Has anyone upgraded the sound system in their Levorg? Just wondering if an amplifier would help or maybe just upgraded speakers or both? The DAB radio seems to work well but a bit more bass would probably improve the system. 

Not a levorg buuuut - replaced the headunits in the imprezas for an immediate improvement, next will be the speakers as they are not brilliant, still missing some bass though and am looking at an underseat unit for the passenger seat.  May end up with an amp but I have been here before and ICE is as bad as tuning, its a slippery slope 😁
