Yours is W205 right? Do you know if your burmester system is stock or if something's been done to it?

On my cousin's C43, from what I remember...

- 4" mid-range
>> where is the mid bass? can't hear bass guitar riffs or kick drums

- 6? 6.5?" footwell woofer
>> where is the low bass? bass drops don't sound good to me

it also feels shouty when you turn it up because there's a lot of mid/highs without mid and low bass to smoothen it out.

we just threw the match kit at it which made the footwell woofers bigger too

FWIW, I hate the way F series BMW drive but their Harmon Kardon is quite good compared to G20 and W205- 7 band EQ, 8" subs for low-ish bass.
We didn't touch the setup in the F80 he later got.

My best guess is manufacturers figured out after the W204/F30 that consumers just want a brand and shiny speaker grille.
They could reuse the same speakers with some tuning instead of giving an actual audio upgrade.
W205 Burmester was only a ~1k upgrade from the base audio on C class.
