[QUOTE="Cashdollar2009, post: 8817270, member: 617476"] Hey everyone, I am planning a build in my 2010 Honda Crosstour and have worked up a design using the max dimensions that I'd like to try to stick to. I am looking at picking up one of the D4S JP23's and running at 1-ohm. Stock alternator - Big 3, Deka 9a34 underhood and Deka 9a31 in the rear for reserve. With stock alternator, I do not see the benefit of trying to drop to 0.5-ohm. Would love the extra power, but hoping this will be enough at 1-ohm in this space for this subwoofer. With space constraints, I'd like to steer towards an aeroport. In doing research I was having a bit of trouble finding suggestions on using an aeroport in regards to port area for this subwoofer. It seems with slot port designs, the consensus was around running port area on the higher side. Example: 40in^2 for 2.5ft^2 --> 16in^2 per ft^3. I'm aware that calculating per ft^3 isn't a rule, but I tried to translate that to basic aeroport rules I'm familiar with and using a 6" aeroport in 2.5ft^3, I came up with around 11in^2 per ft^3 which in the past for me has seemed to be the upper end of general aeroport port ratio on recommendations. I do not have much experience with the Sundown X-Series specifically, so I am wide open to feedback or suggestions.
