6.5's in the trunk must help when you are listning to music in the front seats //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif
and a pair of 12's and a pair of 10's must be so awesome that they dont cancel eachother out and sound different at the same time (specially two in the trunk, and two in the back seat).
caps = not as useful as you would believe.
6x9 = inherantly more distortion than round speakers.
my sugesstion, put the 6.5's up front in kick panels, get rid of the audiocrap subs, put the 10w3's back there. not sure what the lanzar vibe thing is- but you prolly dont need it. headunit was a good buy. i guess the 6x9's can stay if you really like them. but them tweets im not sure of.
