hey every one me and my friend were having this discussion and he told me subs were the most important part of the system i said i dont think so i told him i think its the install or the subwoofer enclosure. my friend has to 15 in kicker cvx ran off of a massive 1500.1 and his friend has to 15 inch kicker cvr ran off of a kicker 1200.1 i think and the kid with the cvr is proly twice as loud and my friend cant figure out why i said it was proly the box and install but the kid with the cvr is sealed and my friend with cvx is ported so i dont know
