power amp into 412 Wattage question

hey all
I recentlly got a power amp (SS) which when running at 8 ohm impedance will push 125 watts per channel. My cabinet is rated at 200 watts (4x50 watt). My question is will I be in danger of blowing the speakers, or will I be cool as long as I don't push it to hard? Can you run more watts into a cab than its rating, in this case 250 watts into a 200 watt cab? I'm almost thinking it's desirable. My head now is 140 watts, and when I really push it, it doesn't sound as good. ( one of the drawbacks of solid state compared to tube). With my new power amp (Carvin DCM 600), I assume I would have to push it nearly has hard. Obviosly what I don't want is to blow my speakers at practice (or gig).
How can anybody answer your question

??? It also depends on your speakers specifications ;)

If your new 125W/ch amp are class A/B, just put it into your 4x50W cabinet. Just see to that nothing blocks the air around the heatsinks, and that you don't push it to hard ;)

And always keep in mind, that amplifier and speaker should match each other......
If I understand you correctly, you are saying your new amp is a Carvin DCM600.

I own one of these. First of all, it puts out 125WRMS into 8 ohm both channels driven. However, in bridged mode, which is how you would probably use it into one cabinet, it puts out 450 WRMS into 8 ohms and 600WRMS into 4 ohms. I have never had a problem with my amp but I did blow a speaker once because of a song going into distortion. If you are planning to use this as a guitar or bass amp where it is likely that you may drive it into distortion I would not use it in bridged mode. Use only one channel or the other.

Actually, it may be sensible to use an overpowered amp so that it never goes into clipping and blows a tweeter.

I would agree with that but the important part of that statement is "that it never goes into clipping".

He didn't say what he was using it for. If it is for PA or guitar, the chance that it will go into clipping at some point is very high. I would not suggest using an amp that is rated higher wattage than the speaker cabinet in those applications.

thanks for the info guys. My cabinet is stereo so I wouldn't be bridging the amp. Also, I'm using a multi-fx (boss gt-6)as a preamp, so I wouldn't be relying on the amp for anything but uncolored amplification. Many I have talked to do this with the DCM 600 and are pleased, as it is very transparent.

this is upon personal experience in pro audio

it is always advisable to over-power the amps to the drivers - to my customers i recommend over pwoering X 2 for my pro audio drivers ie. for 800 w rms I recommend the 1200 Qsc Power Lite or Crest

this is as

pro audio users will never drive their speakers in to distortion unless in extreme circumstances , they are good sound engineers

once a driver set to run below distortion it will not burn out - speacially while being driven by an over rated amp / as it will when powered with a weak under-rated amp

as the under-rated amp will be liable to clip - and with all the clip protection built in , there may be a voltage surge like in an outdoor venue supplied by generators

this clipping and distortion created by the amplifier destroys more drivers than over powereing a pro audio driver in my experience
