Love my 09, but speakers stink
So I am replacing my rear speakers first. Had a new set of pioneer 6.5's sitting in the garage, so using those.
My question is, does this cone shape plastic piece need to be attached to the speaker?? It obviously helps out rattles with the foam attached to it. It also has the screw points that line up to the speaker hole. Do I just need to screw the new speaker into the sheet metal?? Would you use sheet metal screws?
Also, the pioneer has 2 male connectors on the back, one larger than the other. Which wire do I splice and connect to the smaller male connector, and larger one? I see a white/red wire and a black/red wire.
