There are 4 wires running to each rear speaker in the rear, 2 feed the midrange coil, the other 2 feed the "subwoofer" there is no real subwoofer included with the monsoon system. The coupe is exactly the same but with 2 extra speakers upfront, total of 8.
I admitted I have not seen a sedan. I figured the above person would know if there was a speaker in the rear doors.
However, everything I said is correct.
Pontiac advertises the Sedan monsoon system as 8 speakers - two in each of the front doors, and two in the rear deck - again, the midrange is situated ABOVE the subwoofer and is fed a high-pass freq and it's own power from the amp. And it IS a subwoofer below, it is fed only low-pass frequencies. The shape and size does not determine a subwoofer or not, but rather the frequencies it's fed.
However, the coupe utilizes the SAME rear speaker setup (midrange over subwoofer), but yet has THREE speakers in the front doors. The coupe has two more speakers than the sedan's "8 speaker monsoon system".
The correct verbage is "10 speakers in 8 locations". For the sedan, it would be "8 speakers in 6 locations".
Now since it receives a dedicated channel from the amplifying source, the midrange over the sub is called a "speaker". If the midrange was in series or parallel off the same channel that the sub was using, it would be called a "driver".
For instance, if I built a tower speaker system, with one input (positive and negative on it), but had a subwoofer, a midrange, and a tweeter in it, all wired in series, that whole assembly would be "a" speaker, with three drivers.
However, if on the back of the tower I had three inputs, one going to each (the sub, the mid, and the tweeter) and they were all powered by separate channels from an amp, it would be a "three" speaker system.
The same is true of the rear deck monsoon speakers. The midrange is simply mounted over the 6x9 sub in a plastic cage. Rather than locate the speaker in but another location, they mount it over the sub, since the sub is producing only low freqs which are basically non-directional, so the midrange mounted over it does not effect the speakers imaging. You could simply remove that speaker from that plastic cage and mount it in another location - it's not dependent on signal of the subwoofer - therefore it's another speaker. If the mid was physically/permanently connected to the sub, on could argue that it was a coaxial speaker, but it's not.
Now I have not yanked the door panel. So there could be, in some twisted fashion, no speaker behind that middle-sized speaker grille on the coupes doors, but it sure sounds like sound is coming from there, and the schematics list 10 distinct channels coming from the amp.
