i have tried 2 different subs in my box and both get a rattle or slapping type noise with gain a little over 1/3 of the way up at normal play volume. box is custom built 2 cubic ft at 32hz and 1 sub is a rd alpha v2 and the other is a dc lvl4xl. when i swap them out both produce the same type of rattling noise. what could be the cause of this? checked both with a dmm and they are fine there.
