Would love to know as well. Everyone rips me a new one when I say the bass on Tesla vehicles (all of them) is lacking.
I've leased some 15-20+ vehicles in my life and the bass in my Model 3 Dual Motor and Model S Plaid is absolutely lacking versus some very much cheaper cars.
I don't mean it is lacking *always*, but there are definite gaps where the bass just does not respond at all. Others seem to think this is the world's most amazing stock sound system and it isn't. Full stop.
