Hi,
I bought a set of Bose 802 III from a fellow who had torn them apart. When he did that, he tore some of the wires and wrecked the crossovers. I bought them from him cheap and now I want to put them back together, but I need a wiring diagram for the speakers and the crossover. Can anyone out there help me with this problem. I contacted Bose, but I got the runaround from them.
Any help would be greatly appreciated.

WHAT a surprise!!

In any event, some combination of series/parallel should do the trick. What impedance are the individual drivers? An what does the "crossover" consist of?
Once you get then fixed you'll want to peddle them on Ebay unless you also have the Bose processor that goes with these. They require a rediculous 20+DB boost at both ends of the response to even sound half decent.

My gosh is that true? do u need to purchase another equalizer in order to do this? or does the one that comes with it automatically do it? can u tweek it?
My church sanctuary uses a set of them... the whole system, is too complex for me.

Yes... it's true, and the Bose black box that should come with these... if you bought them new.. has that boost curve built in. It's a giant smiley face curve, way bigger than what could be generated with a typical EQ. It's a trick Bose uses on all the speaker systems they produce that use a single small driver in multiples to cover the whole spectrum.. aka 802, 901, Panaray.

Yes it's series/ parallel wiring, but also
series/ parallel with a 20uf and a 5 uf cap,
with several speakers having 3 wires on a
a speaker.
