Good morning and Merry Christmas, it’s about a C180 Limosine from 1999. I would like to build a bass box in my own build in my trunk. I still have a box in it, but with it it is always such a place problem. with the spare wheel dump I’m not quite sure yet, because of the electronics underneath. Whether there can be something broken, if the woofer is right next to it I don’t know. From the inside room the sound is in order, it’s just about the missing bass. And wanted times fra If someone has already done it.
