9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
Hey,
I just bought myself a used '05 Linear 9-3 , I absolutely love the car, but the sound system is completely lacking in bass. I believe I have the 4 speaker system and i was considering adding an amp and sub woofer in the trunk, but i dont know where to find a bass signal, either line level...
