Bonka Posted June 25, 2017 Author Report Share Posted June 25, 2017 I downloaded a sketchup program to look at the SA box design but didn't do anything outside of that. Link to comment Share on other sites More sharing options...
Jessica Posted June 25, 2017 Report Share Posted June 25, 2017 on the second port section, did you factor in the thickness of the first port section in its lenght?\ Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

Bonka Posted June 25, 2017 Author Report Share Posted June 25, 2017 I think I didn't factor that 3/4" in but there's still a huge difference in the box volume. You're not supposed to count the port volume in the box volume correct? Link to comment Share on other sites More sharing options...
Jessica Posted June 25, 2017 Report Share Posted June 25, 2017 let me put it in sketchup and see what i get. lol Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

Jessica Posted June 25, 2017 Report Share Posted June 25, 2017 i get 1.97cuft net using sketchup. here is the port lengths for a 28" long physical port. end correction not included. you could make the port about a half inch shorter and it would probably act like a 28" port Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

Bonka Posted June 25, 2017 Author Report Share Posted June 25, 2017 Ok so I definitely did mess up that 3/4" on the port length and I miscalculated the volume of that dotted section I had in my drawing because I didn't factor in 3/4" there either. I'm now coming to the 1.97 ft^3 you came to. That's roughly 33.25hz. I think this should actually be ok. I know SA recommends 35hz but I've seen people doing 33hz. If not I can recalculate to get closer to 35hz. Thanks for the helping me figure out what I botched there. Link to comment Share on other sites More sharing options...
Jessica Posted June 25, 2017 Report Share Posted June 25, 2017 one other note, your port area is a little low but you should be ok.

Bonka Posted June 25, 2017 Author Report Share Posted June 25, 2017 I'm getting the Hifonics Brutus BRX1100.1D which can put out 800w at 2ohm. I guess I could add more length to the port since the area is a bit low then. Link to comment Share on other sites More sharing options...
Jessica Posted June 25, 2017 Report Share Posted June 25, 2017 you would have to make the port bigger and box bigger and yes, port longer. You might have some port noise at tuning. Not to knock that amp but i think you will be fine. its fused at 60amps so i doubt it would do more than 750 even at 1ohm. doubt it will do 800 at 2ohm Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.
