What type of music do you listen to? If you wanting to go loud ported is your best bet. Also with Kicker L7s the closer to max recommended the better. 4.5 to 6 cub per sub. Your most likely looking at 4.5 in your vehical. If you need correct specs let me know. Also what type of power will be on them?

And where did you pull those port openings from? Those are WAY too small for a L7 15

ZX1000.1? At 6 cube per the total box will be around 13 cubic foot for the pair after you figure port displacement. If you can get some measurments of the area you have to work with i can give you the dimentions for the box. You can also use the box calculator on this site to figure it out for your self. Port should be 3 1/2 Width 16 1/4 Height 13 3/4 Length Fb= 30 Hz and is .42 cubic foot of displacment which needs to be added to the net 6 cubic foot. So each chamber for the sub should be 6.42. Easy way to figure it is to make it 13 cubic foot. Put a baffle/partition wall in the middle to seperate it into 2 chambers. By the time you add the baffle, bracing and port per chamber you should be right on the 6 cubic foot mark. If that won't fit let me know and i will give you the specs for the 4.5 per

In most cases yes. Kicker actually recommends it that way as well. I also always try to do it that way. If for some reason one sub blows it will help protect the other by it still being and operating in a correct enclosure. Usually the only way i run more then one in a single chamber is if im dealing with space restraints because the sub will act as if it is in a little bit larger enclosure. Also output and sound quality are generally better in seperate chambers.
