what will happen ?
if i run a 1200.1pg amp (1554w amp) to a 27kx focal sub (600w max sub) http://www.focal.tm.fr/accueil_en.htm
ftp://208.187.38.55/Phoenix_Gold/Man...00.1manual.pdf
what will happen ?
this is sq set up
ftp://208.187.38.55/Phoenix_Gold/Man...00.1manual.pdf
what will happen ?
this is sq set up

Exactly what sq said...you don't have to set the amp to use all 1200 watts, just set the gain in proportion to what the woofer can handle...even better with an sq setup set gain on sub to blend perfectly with your fronts.

Don't agree with the above but maybe I am picky. An amp makes the same amount of power regardless of where the gain is set. The amp is going to make it's power into the load as determined by the sub. It should be fine provided you allow the voicecoils to cool. If you keep any sub pinned or even close to it's thermal limits with any amount of power and it cannot dissipate the heat, that sub is going to fail. As this sub appears to be a 4 ohm driver with a recommended power handing of 300w rms, it may be a good match depending on the 4 ohm rating of the amplifier to be used.

Here is a great link on a similar discussion.

and as far as how much power the sub will be seeing... as per the manual, hooked up into a 4 ohm load, @ 12.5 VDC, it's putting out 250 watts, so even if you get double that because of a little higher voltage, I'm sure it will be fine, if the volume is kept in check...

i think that if you grab a test tone.....1khz and have the gains al lhte way down......and put your leads from a DMM onto the speaker output.....you will get a reading.....and if you raise the gain.......you will see an increase.....how much of an increase is depends on a few things......but i know that it will increase.
so i dont think it puts the same power output with min gains as with gains higher.
but you can also achive the same output on the speaker side with gains pinned and gains low with a line driver......but how much of a difference in sound i do not know.
any one know the answer to that one?which is better sq
high gains/no line driver = x output
low gains/linerdriver = same x output
according to our tests for spl i know what we encountered. but im curious as to what you sq'ers have found.

ok how / why can this be 12vds = 250x1 then 14.4vds=1200x1 and and 14.4vds=1400(dynamic power)
what # do i need to look at 250/1200/1400?
