deadening the doors will make a significant difference, tuning will make a big difference, as well and perhaps you need some more power to them. i actually had to EQ out some of the midbass because it was a little too overbearing. what amp are you running to them, and where are they crossed over at? i was running a boston GT22 on the mids, and a GT20 on the tweets, crossed over at between 50 and 63hz with a 12db slope. when i turned my subs off, it still sounded like there was a 10" sub in the center console.
do some tweaking around with them and you'll get more midbass than you can handle //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif the pro's will hang with the Z's... until you start crankin it. then the Z's pull away from them like no other //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
