Ok when my sub is turned up really loud I know it is not bottoming out. I am pretty sure it is clipping. I will turn it up and on the high notes it just sounds normal, but on the really low low's, it starts to pulse on whatever tone it is on. kind of like a soft popping sound...This is clipping right? Which means the amp is pushing all it can and is not getting enough power to it or something right? Does that mean the sub can still handle more power if it is not bottoming out yet? Maybe I should get a bigger in line fuse?
