something weird but in a good way...i dont know who else had this but i just put in a 10'' sub in my car today and drove and to my suprise....the z fumes are 80% gone. i know the sub can grab air and then blow air but damn....my fumes are nearly gone. im happy with the sub..hehe ill update my page to show how my sub was placed and designed...maybe if yah bored, make the same box...you can try and see if you get same results...laters
