[QUOTE="Terrum, post: 8812876, member: 657229"] As mentioned in a few other threads, I'm looking to go from a single SA-12 D2 Classic (750W) to dual SA-12 V.2 D4s (2x1000W). I've got the amp (SALT-2), waiting for the subs to be delivered, and now I just need to get a design and box built. My current SA-12 Classic's box was designed by Buck but unfortunately due to his inability to design currently I've had to resort to doing my own or find someone else to do one for me (or get help from this lovely forum). I decided to spend the day measuring my trunk to figure out the absolute maximum I can comfortably fit in there for an enclosure that I will be able to take out at ease when I need to carry luggage. It was a huge pain having to measure a perfect rectangle whilst taking into consideration the dimensions of the door frame, parcelshelf and the slant of the seats, but now I have dimensions of a box that I threw together on subbox.pro that I can comfortably fit into my trunk: [URL]https://subbox.pro/en/b/6faST67qs[/URL] I took 0.75" off the depth to allow for a double baffle during the actual build. My current box is tuned to 30Hz but I wanted to tune the new box slightly higher this time (32Hz) so that's what I've set the box to on the link above. I'm not entirely sure what I should have set the 'Port Area' to. Sundown's site recommends 26 sq in so I just doubled it because there's two subs, although I'm sure that's wrong. I'm just looking for someone who can check it all over for me to make sure it's fine, or anyone that can offer opinions/tips/discussions etc to help me get the best out of my box, or if someone can recommend a designer that has lots of experience building boxes for Sundown subs and can help me achieve the best output etc. Thank you for reading and I look forward to any replies :) [/QUOTE]
