[QUOTE="CPolarBear, post: 8802799, member: 686395"] I have two older Pioneer 12" subs. If memory serves, they require 2.0 cf for a sealed enclosure. Would they work well in a prefab dual sub hatchback box (angled front) that has 1.25 cf per side/woofer, if I were to drill out some port-sized holes in the center brace to merge it into a 2.5 cf sealed space that both subs were sharing? This is a low powered system, with about 300W shared to both subs. Would doing something else to the enclosure be better (I don't' have data on me to figure out what a ported enclosure should be for it, though that 1.25 seems pretty close to what I remember). Putting in a 2010 Nissan Altima, thought the angled front would work well facing into the rear seats through the opening from front to back. Using sub-out from a Boss head that is set at 80 hz... I also considered a sealed 1 cf box and doing a clamshell isobaric setup at about the same cost. Again, these are older subs I already have on hand or I would be pursuing a different options/install. Just looking for simple options, not gonna get into 4th order bandpass or other fancy stuff, this is my commuter car and the upgrade is as much for bluetooth and Android Auto as well as reasonable sound. Not worried about high SPL. [/QUOTE]
