I'm putting a system in my van. I have a really nice system (3 10s under back seat/front and rear door speakers) in my chevy duramax it's not super loud just a crisp sound super clear and I'd like to put something like that in my van but I'm not sure what im looking for dont know much just basics its a sprinter van I'm putting a wall at about the half way point to separate the cab so it's not going to be all open I was thinking about putting two JL W7 12s under the seats in sealed boxes and maybe a 10 against the dividing wall woild this be a crisp system or pretty gnarly bass and what would I need other wise
