Hello. I am relatively inexperienced in the audio world although I feel I have a grasp on the basics. I am in the process of buying a new amp and i was wondering if anyone could point me in the right direction with maybe a wiring diagram.
My speakers:
(3) MTX P215H Loudspeakers. These include a tweeter, 2 15" subs, and a passive crossover each. Each has 300W RMS. 1200W Total power. 4 Ohms.
(2) Behringer B212XL PA Speakers. Continuous 200W. Peak 800W. 8 Ohms.
I have a 2 channel amp now that is underpowered for the speakers. I'm really looking for some solid guidance so any advice would be appreciated. Also, if anyone has time for a quick wiring diagram with the suggested amp type that would be even better.
I want to buy a quality amp that will work and sound great.
Thanks, Treyning

Okay, here goes.
If you take the cabinets you have and you want to feed them all the same signal (not necessarily a good idea), then you need something that can drive 2ohm at each side all day.
I'd recommend more amplifier channels, so you can feed the 3x 2x15" cabs the same thing, seperate to the Behringer 12"s.
If you're sure you want a quality amp, grab a Camco Vortex 4. Make sure you've got a solid mains supply.
Now that you've had a look at the prices on those, a Behringer NU3000 will do the job. The DSP version has EQ and crossover filters built-in. The sound is very good for the price.
In your position, I'd get a Behringer NU4-6000. Give each 2x15" cab an amplifier channel, and link the 12"s together on the last channel. Add a processor and you can EQ/cross over/delay speakers as you like. Much more flexible than a simple stereo amp, and you won't be running it as hard: 2ohm on each channel is tough for any amplifier. Putting 4x 4ohm loads on the 4-channel amp is much nicer.

Chris thanks for The advice. I'm leaning towards the Behringer NU4. My only question with that is that it shows it to be 4channel @ 2ohms and 1500W. If I'm running the towers each on a separate channel they are 4ohm. This might be a stupid question but is it okay to run the 4ohm towers each on their own 2ohm channel?
FYI the 15" drivers in these boxes are not subs they are woofers. And do you actually have 3 of these boxes? Seems an odd number to have.
What amp is that?
How do you usually arrange these speakers? I can't see the 12's being very effective next to the 215s so are you using these smaller cabs as monitors? I agree the inuke 4-ch amp would be a good choice because you just can't power and EQ the boxes effectively with a 2-ch amp.

2ohm is more demanding than 4ohm. If you've got an amp that's designed for 2ohm use, it'll be ticking along happily at 4ohm.
