1-12'' l7 w/ kicker 600w ammp. in both a ported and sealed box it made a wierd "flapping" noise when it hit hard, the gain is mybe half and the HU vol. is almost 9/10. it only happens when real low bass tones come on. i turned the gain almost off and it hits fine, but it doesnt hit as loud now w/the gain so low. it didnt used to do this, any suggestions?

Port noise. The port is too small, increasing the velocity of the air coming out. It's pretty common.

yeh but he also said a flapping noise, which could also be his box is tuned to high and he's playing low notes which are under the tuning frequency of his enclousre.

He said that it made the "flapping" sound in "both" the ported and the sealed box. If it made the sound in the sealed box it could not be port noise.

Hmm. Will, when it makes the flapping noise can you hear any bass? You could just be playing frequency's too low for your sub to play properly. Some subs don't go as low as others.
