Crown XLS2000 & XLS1000: How much ampere do they pull?

Based on threads on this sort of thing in the past, you should not have to worry about all amps trying to pull their peak amperage at once. Also, it takes a bit of time to overload a circuit. The amp may pull peak current for very short periods of time, but perhaps not enough to pop breakers.

People have hooked their entire home theater including multiple amps up to a 15 amp circuit and not popped . I have a plasma TV, receiver, and two amps plus some other sources like PS3 and Tivo AND lights, and have no issues on a 15 A circuit. Never blown a breaker, but I have dimmed lights, I think mainly if I turn on gear at same time.

I am no expert, but a single 20 A circuit for your amps would likely ensure no dimming of lights and such under any inrush conditions (the Crowns might have inrush limiters in any case.) And ensure the amps would not intefere with other gear. But I would think you would then increase chance of ground loop hum by having amps on one circuit and sources and pre amps on another.

There might be a DIY/HT forum here where people have more info on this topic.

A 15A circuit (using the 80% rule) can support 1440 watts and a 20A circuit can support 1920 watts. So for example, if one (or any combination) of your amps is consistantly outputing 1700 watts, then you would need one dedicated 20A circuit for that amp and a seperate dedicated circuit for anything else.

Ah, this is not for a home setup. We are out of my league here A larger room calls for more power, so I have no advice, sorry.

The reason my lights dim, with amps powering up, is because they have large capacitors which are charging, thus creating a high current load for a brief period.

I own (4) XLS 1000's and (2) 1500's.

And while they're just in my living room, I can tell you that I've never tripped a 15A breaker upon turn-on...all 6 at once via 12 volt.

I can also reach oppressive (100+ db) levels in my 30X16 living/dining room with ~90db sens speakers with and never see my Panamax drawing more than 8-10 amps from the wall and that's also with my power-hungry Kuro running which is good for 5-7 amps on its own.

Long story short, on a 20 amp circuit I'm pretty sure you'd have to be pushing these near/past their limits to run into problems.

EDIT: looking now that you'll have (4) subs, I'd normally suggest a second line, but again, you're talking about "just" a couple hundred watts for the pairs coming from the 1000. Will that accomplish your spl goals? Perhaps they're horn-loaded designs so the answer is "yes". ?

Room size/listening distance and desired output levels are going to be the keys to the city, here.

I would also tell you that you can be fairly certain that simply dividing their maximum rated power into a given impedance by 120 will yield an amperage that will be ballpark enough for your purposes.

So, if you're running a pair of 8 ohm cabs off the 1000, you can figure 215 watts aside / 120 = 3.58 AMPs.

That's MAX continuous, of course there will be peaks, but unless you're running a 15 channel stereo array, I doubt- even collectively- that they will trip a 20 A breaker.

Regardless of the size of your room, the reality is these amps are just 2-400 watts a channel and are only going to draw so much out of the wall.

How large is this room, anyway, because at some point you have to start accounting for 15 speakers enhancing overall output unless we're talking about at truly gigantic space, in which case, these are prolly not the best amp choices to begin with.
