fiberglass kickpanal noise

I made some kicks for 5.25 mb quarts and separates when the mids hit certain note it sound almost like they are blown they make a rattle like noise could this be a weak area in fiberglass or to little air space it only happens with a certain frequency and not when they hit harder notes any help would be appreciatedTcheck

what frequency are the kick crossed over at? what amp are you running to them? are the kicks enclosed or open in the back?

you could be getting some resonance from the enclosure, MB Quart generally reccomends no enclosure for its mid bass and midrange speakers, so you could try cutting the backs out of the kickpanels or try to install some dynamat dynasorb mats in them or maybe some polyfill, experiment with trying to dampen the enclosure before hacking them up though.My mechanic told me, "I couldn't fix your brakes, so I made your horn louder"
