wind (noun) - air in natural motion, as that moving horizontally at any velocity along the earth's surface.try it ported.
you dont have a problem.
give it more power if you want more output.
mine "rumble" and i can feel the wind from them.
wow. it seems like you have a cold front inside your vehicle. watch out for precipitation.
anyway. whatever you are describing with your 'rumble' is normally linked to distortion or unwanted resonances of your cars interior. why on earth would you WANT your car to rattle? you seriously do not make any sense with your description of things. just send me the idq and put your JL garbage back in and im sure you will be happy. ill even give you a few dollars for it if you want. i have had 4 idq's in the past and present, and i have never had a single issue with them. i also never had a 'vibration' problem.
if you want to feel the bass, go get some tactile transducers.
