hi all, has any one fitted a sub with built amp to a after market head unit (V5754)
what I need to know is what phono leads from the head unit do I use,
because the white thin plug that goes in to the back of the unit has many phono plugs coming from it,
ie 2x white and 2x red marked (front right/front left) (rear right/rear left).
but the two iso plugs that power the unit and speakers have 2x phono plugs from it (1 red) (1 white) with stickers saying (onstar)
so if any one as some info on
