well lets say i turned the volume up on my HU all the way up on a sub that's rated at 1000w rms, and the amp only puts out 800, would that blow it or over excurt it? just wondering
well, depending on the HU, it will clip the signal to the amp, and then the amp will amplify the clipped signal and send that to your sub. you should set your gains with your HU at no more than 3/4 volume.
and no, you won't blow that sub with 500watts....it is when it isn't loud enough and you either
A. crank the HU some more B. crank the gains some more
that will cause the amp to clip and blow the sub.
the reason most people recommend more power than necessary is b/c you will reach the subs xmax faster with more power than less(so you will hear the sub becoming sloppy) and back the volume down a little, instead of it not being loud enough and cranking the aforementioned a or b and thus blowing the sub.
