I am confused about how to hook up some speakers for live sound. I have 2 cabinets with a 15 and a horn, and then 2 other cabinets with 12s and a horn. I want the 15 for the low end, and the 12s for the higher end. My plan was to get a crossover and hook it up to one of each cab. Is the horn in the 15 cab going to cause problems, or will it more than likely do nothing since the higher end stuff is going to the horn in the 12s cab? Is there a better way to use both cabinets? Should I just hook all of them up as the mains and screw the crossover?
Next question is, how do I power them all? If each cabinet is 1,400 watts, do I get a 1,400 watt power amp for each speaker, or one for each pair of speakers since the amps have two channels? Do I get 4 amps or 2? If I get 2, do I use the one amp for both 15 cabs and the other for both 12s, or do I use one amp for the speakers on the left side and the other for the speakers on the right?
