Flipmo101 Posted April 11, 2019 Author Report Share Posted April 11, 2019 My box (outside) dimensions are 40w x 16h x 14.18d will be inverting my sub to save volume and originally planned on using an 8” (actual diameter 7.5”) x 21” long standard port which would put my recommended port area almost exact to spec 45sqft. Tuned to 31hz. my issue is that, using this standard port, would require stick out of at least 14” due to the available space in my vehicle since I cannot exceed the box dimensions so my hopes is to utilize a flared port to counter this issue. Also, my port and speaker will be facing toward the roof as limited space requires this in my suv. I hope that makes sense, thanks for the replies Link to comment Share on other sites More sharing options...
