kl0wn Posted February 12, 2010 Report Share Posted February 12, 2010 Well, I did purposely send my sub a clipped signal of 40hz to see exactly how a major clip sounded like. And the sub was moving no where as much as it does on an unclipped signal. So I was just assuming that it made it so the sub less than normal and that's why it couldn't get rid of the heat that well.

dwz Posted February 12, 2010 Report Share Posted February 12, 2010 I thought my subs were clipping. Till I put Dynamat Xtreme on the sheet metal behind my tail lights. Suddenly I no longer hear that rattle. Quote Link to comment Share on other sites More sharing options...
