just throwing it out there, dont care about brands, amp wattage, or box porting Hz
just what would chose, if all option were in same car and same size box, as in most people situation for the average car not willing to give up to much space, for a good all round package, lets assume 2 cuft including sub and port displacment
so remember not all options will be withing the recommended parameters
with 2 cubes to work with total, one 10" ported if i was on a budget/not trying to spend a fortune. if i had some cash to spend then maybe 2 12" sealed but find some woofers that like small sealed boxes.
