Box design help with port length (Torres and SketchUp inside)

[Skrilla]

what sub and how much power

and you still need to tick up/up

edit

what car? 60" width is near impossible for most

HDC318's on an AQ2200.

It's for my dodge ram.

With 2 common walls and same box height and same 10 inch wide port you can only go 14 inches long.

Wait, I thought I could go up to 18.99" on a 2 common, and up to 13.99 on a 3 common? If my port is 17" long on a 2 common, that leaves 7" from the bottom.

With 2 common walls and same box height and same 10 inch wide port you can only go 14 inches long.

why is this

a 2 common wall port splits into 2 port to create a T-port

and in doing so the width changes to 5" across the back

at 18.99" long there is no L2 and that is the length of the port

at 19" the L2 is 0.75" (port wall thickness) giving you a port length 24.75"

so 19"-24.75" is a non achievable port length

Really, did you look at his design, he isn't doing a T shaped port.

you cant go closer to the back of the box than the narrowest width of the port so 10" in your case.

[Skrilla]

Ok, got it!

[AMI CUSTOMS]

The port opening has to constant throughout the entire length, so your port is 10 inches wide, that means the leg of the port can only go down 14 inches, in your case 12.5 since your baffle is 1.5 inch thick being part of the port length. That would put it 10 inches from the back wall of the box making the opening and exit of the port the same which they have to be.

his first drawing was side port (*3 common wall)

if he does a centre port (2 common wall)

a 17" port length is doable (an L1 of 15.5)

giving him an opening of 7" on both sides, equal to the same as 14" of opening

[Skrilla]

Confusing me... lol

[john253a]

do you plane on port on side or port in centre?

[Skrilla]

Center port (2 common wall).

So can anybody else confirm this? I'm just a little confused with getting two different answers...

I know I can't go closer than 10" from the back wall on a 3 common port, so does that mean I can go up to 5" deep, each side, from the back wall, with a 2 common port, which is equivalent to 10"?
