I recently picked up a used Ampeg SVT 810. I'm not sure exactly what model it is. The jackplate only has one 1/4 jack and that's all. Anyway, it was missing the second row of speakers from the top. The guy that sold it to me drew me a little diagram showing the order in which to wire in the replacement speakers when I got them. Of course when I picked up two new speakers I couldn't find the diagram so I just kinda guessed it. I'm getting sound out of all 8 speakers but I'm not sure if its wired correctly. Can somebody please explain the order in which to wire the speakers into this cab? Thanks!
