How do i wire a set of MB Quart QSD164.
The x-over has the following in the respective order
input left
- +
output left
S- S+ W- W+
output right
W- W+ S- S+
input right
- +

Now the input are self explanitory, what does the "W" and "S" mean? This particular set is for add-on midbass but i want to temp use them for rear fill. They only have 1 x-over and no tweeters. The X-over is pretty big, where do i stick that into?

I also got a JL450/4, now how do i wire this thing and where to i install this? When i ask how to wire it, i mean do i really have to run speaker wire from the radio to wherever the amp is then run back wire to the x-over then run more wire to the speaker.
