Most JL Audio subs are medium 'Q' and will function effectively in either sealed or ported enclosures.
Sealed will give you a higher but more gradual low frequency roll-off.
Ported will give you about 1/3rd octave more deep bass extension before rolling off far more abruptly. In a ported SQ alignment you can expect a + 3 dB increase in the deep bass output.
So if you can afford the much larger enclosure displacement it makes sense to go for the extra output of ported, especially with the serious losses you will incur within the passenger side locker.
Normally I would choose the added output of ported, but if given a choice between direct-radiating and sealed on the driver's side versus concealed and ported on the passenger side, it's a no brainer. Sealed on the driver's side. No contest.
If you do go to the passenger side you should have a large vent equal to or larger than the woofer surface area to allow the bass energy to flow from the compartment. Otherwise, you will have nothing more than a tactile boat shaker and a very poor musical bass maker.
