amp cutting out..?

[Etac 10+ year member]

anyway i hooked up my *new* amp.. supposed to put out 284 x 2 @ 4 ohms... i set the gains to 225 watts.. and the volume at 25 of 35.. once my music hits a certain volume .. it will cut out almost instantly (has to be heavy sections of the song and usually volume 22ish) and will come back in like 2 seconds... cut out again in 2 seconds ect... so its not overheating.. and if i turn down the volume a click or two there is no problem whatsoever...

im hoping this is a ground problem - but the only way to get to my ground.. im gonna have to remove a lot of stuff.. so i was just curious what you ppl think it might be.. i hope its not that the amp cant handle the change in impedance.. i dont think its too big of a voltage drop cause im only pushing like 700 watts.. and i dont htink its a bad amp cause my old jbl had this same problem only it seemed to take a little more before it cut out..

and i would also like to say thankyou jbl who accepted my broken amp and replaced it with a new one no questions asked =) and for those who say most amps sound alike.. well i been using my old sony while this exchange was taking place.. and my jbl sounds so much clearer that its almost like im listening to new speakers..

Did you ever figure out what caused this? I have the same problem with my

infinity 7541( same amp as the GTO 75.4). It works fine when the channels are not bridged but when I bridged it the amp now cuts out at higher volumes.

is it going into protect or shuttin off ?

It goes into protect for a second then comes on again. It does this continuously unless I lower the volume.
