these subs are rated at 375 RMS you are going to run 2 of them and what ever amp you get  is gonna run at 1 or 4 ohms i take it these subs are under rated with crossfires quality  the crossfire is the best amp out of what has been spoke of  if the subs can take 500 rms go with the crossfire amp and run it at 1ohm  and also if there is an in store warranty for the subs get it

yeh thats what i want to do.  i want to run the subs at 1 ohm and get 500 rms to each one, and that should be VERY loud.  i'll ask the guy at the audio place if the subs can handle it, if not i guess i'll have to put them at 4 ohms and see what happens

they *may* in a ported box, but if you put too much power to them below the frequency the box is tuned to, they are toast...

well i wonder if there is anyway to wire them to 2 ohms total?  cause i think that would give each sub 250 rms watts, which wouldnt blow them, but should be pretty loud.  the only options i see are wiring to 1 ohm total or 4 ohms total, and 4 ohms prolly wouldnt be much louder than the system ive already got

ok following up on this i went up to the audio place a little while ago and found out that the 1000D amp is rated at 12.5 volts, so it actually pushes more like 1300 watts at 14 volts.  The guy up there said that the 2 15's should definitely be able to handle all the power at 1 ohm, which he said would be around 650 or 700 watts apiece.  I don't see how that is possible though because the RMS ratings of the subs are only 375 watts.  Granted, they will be in a ported box which should let them handle more, but not 700 i dont think.  Any ideas?

i am running about 300rms to each of my subs and they are rated at 200rms some highend stuff is under rated and can handle more power

well hopefully thats whats gonna happen with the crossfires.  the guy said that the 12" BMFs could handle the 1000 watt amp, so he said my 15's should be fine.  im hopin so

ported box will drop the power handling vs. a sealed box...

You should set the gain control on your amp using a digital multimeter. since you are using an amp that is going to put out so much more power than the subs are rated for. Just do a search on this forum for "setting gain."
