[QUOTE="LongThrow, post: 8743203, member: 661351"] It's been a long time since I've visited this forum, social media seems to have stolen all attention from the old forums. I have 2 DD 9918s that I'm wanting to put in the back of my crv. I can't wall it off, as I have to keep the rear seats (I have 2 kids now, life comes at you fast, eh?) I have a max dimenion of 42W x 24D x 24H. I am using 2 8 Inch ports, 22 inches long. From what I am able to math out, I will have to do subs up port up, with my math I came out to 11cf net, after all displacements, with the ports sticking roughly 4" out of the box, thats give me a tuning of 30-31hz, simulated port velocity of 32m/s @ 30hz. I will be running 2 Synergy 8.1s, 1 per sub, roughly 10kw per sub. Anyone see an issue with this design? I know I'm kinda short on port area, might end up with some port compression around tuning, but this is the best I can do fitting 2 big ass 18s in a crv. [/QUOTE]
