JL's are great if your looking for somwhere inbeetween lotsa sound but not the best quality. Or you can to a really high end shop that wont sell much of anything you find at best buy visions etc and get great sounds quality but you wont get anything showy or extremly loud unless you want to pay a fortune. If you liked your JL's in the past they are still just as good. MB quart not so much if you ask me. Im very disapointed with everything iv bought from them. Kicker seems to be right around the same SQ and loudness as what you have had before if you can find it cheaper. There monoblocks are very high current and will pound on the alternator
