Dude Going from your w3vs's to 10" CVRs would be a downgrade in SQ and about equal for output. JL has won national consumer electronics shows with all of theier subs. Kicker has had some sucess in national SPL events but JL has some w7 setups that near as loud and have some SQ. JL also won the award for the best sounding car at CES 2005 but some smaller companies just couldnt afford to comptete they may sound better than JL. Ok there are better companies than JL for your money.
