got questions about installing subs in rear deck

Got a 2002 Maxima and thinking about just installing some 8's in the rear deck. first question is are infinite baffle and free air the same thing. I understand that with IB you seperate the front/rear sound waves and all but not sure if free air is the same. Any one out there have this type of setup? What pair of 8's would work well with this? And any info will be appreciated. Not looking for any bone crushing bass, just some nice low end to fill end and complete the system.

its the same as with your door speakers. the better the door is sealed the more midbass/bass youll get. Youll get some, but like i said the better you separate them teh better the bass will be. My infiniti was sealed up good in the trunk and it got loud and low off 6x9s and my pontiac is not so the midbass is a little lacking.

i know that in IB the trunk needs to be sealed off completely, is it the same for free air?Or as long as I mount the subs on a baffle before mounting them to the rear deck? Sorry for the questions, just a lil confusing to me.

may sound dunm but what if i just put some 8's in a sealed box and mounted them up to the rear deck with subs facing up into the cabin?

that would be best case, free air and ib are the same thing, having a box on them would be best but probably a ton of work

well, i already have a sealed enclosure that i built for a pair of 8's about 2 years ago but never finished the plan. Think its like .4cubes per side or something. Shouldnt be too hard to mount it up to the rear deck. Think i may try that instead of the freeair plan

what about the cdt CL-69 speakers. Wonder if these would work well mounted to the rear deck?
