Alright, here goes the technical explanations.

Say I have a Behringer EuroPower EP2500 Power Amp. Specs: 2x1,200W @ 2 ohms; 2,400W @ 4 ohms bridged.

If I wanted to amp Four(4) Peavey PV 215 cabs. Specs: Handles 700W program and 1,400W peak power. 4ohms Nominal Impedance.

Daisy Chaning 2 cabs to each side of the amp would give a 2ohm load, with each cab getting about 600 watts.

Is this correct? Is it safe to run like this, or is there a better way?

I know that there should be more power in the amps than the speakers can handle so distortion doesnt occur, but if I set each speaker to receive about 500 watts, there should be no distortion, giving me about 2000 watts total.

Let me know if I am wrong so that I can finally build my Dream PA system.

Ok, I'll just say a few things. The 2-ohm ratings for the EP-2500 are actually more peak measurements at 1khz than acutal RMS output. Depending on what you're playing, you'll actually get more like 6-700 watts out of each channel at 2 ohms (~1300 bridged) depending on what you're playing. This is taking into account the full frequency spectrum and a more continuous measurement.

Wiring 2 cabs to each side in parallel should yield ~350w to each one, however, you have to take into account minimum impedance of the cabs. Running like this can also shorten the life of the amp and lower it's reliability significantly. In the long run, it'd be much more reliable to give each cab it's own amp channel at 4-ohms supplying each amp ~700w based on a reliable 20hz-20khz spec and should be much more satisfying in the long run. This way you can get full performance out of the cabs without damaging them or the amp as quickly.

All in all, I'd recommend 2 amps if you want to do it properly. You could also run each pair in series for each pair at 8 ohms, then run those pairs in parallel to 1 amp for 4 ohms bridged, although that'd be the same as what you described, except the amp would have more woofer control. I'd still recommend using 2 though, but probably the last setup would be fine.

The reason I know this is because I'm considering (most likely will be) using the EP2500 as an amp for my Infinite Baffle with 4 FI Q18's. The way the cabs are rated, they'll take 350rms, 700program, 1400peak. One amp should be able to provide the watts if you aren't interested in dynamics as much as volume.

I'd run them (like I said) with one pair in series and the other in series, then run that pair of paired cabs in parallel for max woofer control (sound quality without losing volume). Did I explain it well enough? Neither of the specs are totally up to snuff and so they should go together well.

Yeah I get what youre saying, but if I was to give one cab for each amp channel, the amp would be putting out 2ohms and the cab handles 4ohms. Is it safe to run like that?

Ah, I see you don't quite understand how it works. I'll try to explain a few things. It's hard to explain the way I want to, so I'll just say what's important. If each cab is on 4-ohms with that amp, the amp runs from a 4-ohm load. That means the cabs will each get about 700w from the amp. When I looked further into the cab specs, I discovered that the cabs can really only take 350w RMS. I would recommend using 2 amps if you're worried about damping factor and how good it sounds, but don't turn it up that loud. If you're worried about turning the volume too far and damaging the speakers, you can get a BFD and set it up so the speakers are flatter and set an output limit so it never taxes the amp or speakers. What is it exactly you don't understand? I'm not quite sure, but I can see you don't quite understand the relationship of amps and speakers.

Im am just unsure about the ohms. What you are saying is that one cab on each amp channel would give me good clean power. How high would I be able to set the amp? All the way or half way?

I'm sorry if this is too juvenile for you, but I want to make sure I make a legitamite purchase.

You could use a BFD and set the maximum output (and equalize for cleaner sound) by using an SPL meter.

I think I've seen you on eCoustics?

I cant remember if I have posted on eCoustics, but I have been there, thanks for your help. I am pretty sure I understand now about the PA though. Thanks again.
