the cvr will rattle ur trunk if u get a ported box i have them now and they are pretty good for the money. wire them up for 2 ohm bridge and u be set. but like u said the l5 is way better but for 600 dollars and 10 inches that is not good. u could buy one 15 inch l7 for that then u will be rattling ur trunk for sure. and really u should make ur own box it cheaper. but u deff need it ported for it to be loud so i would say out of them two choices the cvr cuz it worth the money
