W205 bass speakers

are these plug and play ? Did you need an amp or audio running ?
Stock location is tuned for certain frequencies i’d guess 60hz. And it hits great there.
Under 30hz i dont believe the factory outputs but I’d need to double check that.
on my cls i was able to grab low level factory sound for the subs to amplify. I think u could do the same here
i also did focal center channel non coax and it sounds great. Both shipped are under 1k
