PA Speakers and Wiring help

[DubSound]

Hey guys, i was hoping i could get some assistance with this PA situation.

I have:
Crown 1000 watt power amp (2 channels)
2 15" PA monitors (not sure of the impedance)
2 horn tweeters

The cabinets have 1/4" jacks and regular speaker wire inputs

I am confused as to how i can wire all 4 speakers together with 2 channels, if its possible at all, or if i need to get a separate power amp for the tweeters.

Any help would be appreciated, as i am not very experienced with this stuff.

Thanks

You will need an active crossover to use all of your speakers.
Mono out -> crossover high out -> power amp ch.1 -> tweeters
----------> crossover low out -> power amp ch.2 -> monitors

BTW why do you need to do this? Do your monitors not have tweeters?

Thanks for the input. I'm not sure that I need to have all 4. But someone donated all the stuff to my band so I figured I would try to use it If I could. The monitors do have tweeters so I'll try those first.

Thanks again
