How Many square inches do I have there??

What should I do with the port? Make it longer wider or taller?

I'm just now learning how to make a box and tune it so

It's kinda complicated :/

Right now you have 36. I would make the port 5 inches wide and 25 inches in length

How tall would you make it though?

I wanted to put the port along the bottom of the box under the sub?

And what would that put my tuning at?

Edit: ok how bout the port 5 inches high

12 inches wide and 25 inches long?

That's 60 square inches of port right?

What would the tuning be?

Around 32hz?

For one L7 15, I would do 8 0 sq inches of port MAX, unless you aren't going to put shit on it for power. That sub needs between 5-6 cubes to get LOUD.

my dimensions i have now are

outer dimensions

L- 16"

W- 30"

H- 16

comes out to 3.46766 cubes internal

any bigger and ill have to build it in the trunk and im not doing that..

not much room to play with and i want it ported

sub will be ran at two ohms on a hifonics brutus BRZ 2100.1D with specs are 1400watts at 2 ohm but the car is all stock electrical so it probally will be seein barley more then 1000watts

i want it ported with a slot port tuned no higher then 36hz

i was thinkin a port 10 inches wide and 5 inches high but how long??

sub facing towards the seats and port firing driver side

internal width is 28.5 inches

any help is appreciated :drinks:

If you have that little room for your L7, I recommend selling it and getting something that requires more like 4 cubic feet max instead of 6! I have one L5 in my truck in a 6 cubic foot box, and it SLAMS, check out my video if you want to. But the one thing I know about kickers is that they love their space. A single L7 in a 3 cubic foot box (ported) on about 1500 watts would get owned by a single L7 in a 6 cubic foot box on 950 watts... You will be disappointed if you decide to build such a small box for your sub.

With those figures, 26 long for 36 hz and 30 long for 34, but with a port that long that is going to take away more net and make the box even way smaller. Cuz at 36 hz tuning you are at a 1.0 cube worth of port, so that brings your net cubes down to 2.4 without the sub. WAY too small, you would need a shit load of power to make it do anything. You should consider either selling the sub or making a sealed box that is 3.4 cubes.
