Help with a ported box for my 15" L7

[prmnt]

I got a kicker 15 L7 for 80 bucks and wanted to make a ported box for my truck. The only problem is i only have about 32 long 21 deep and 16 tall. Is this enough space to make it sound nice? Supposedly from some websites the box will be somewhere around 6 cubic feet.

That would be around 2.5-3 cubic feet not 6

you dont have enough space to properly run it

You can get like 4.2cubes with that space. It will be enough to make that woofer bang some

Where did you get that calculator from

Xplicit audio app. It's worth the $1 it cost

I carefully measured where my box will go and got these numbers 35-width 22-depth 16-height. Plugged in those numbers to the app(its free now), and it jumped from 4.2 to 4.7. Not sure if .50 cubic feet is a lot but im assuming it helps right?

Every little bit helps. Run an aero port instead and you'll gain even more net cubes. One 8" aero at 17" will give you about 5 net cubes at 34hz.

Go round ports instead. you'll get 5 cubes which is pretty acceptable for a 15 L7. Basically build a square box and cut the hole for the sub and cut a hole for the sonotube and glue the sonotube to the box. Make sure the box actually slides into the car right.

How would you do that? Lol Do i just make a hole and put in a pipe? How big does the pvc pipe has to be if the box will be 22inch front to back

look at the picture. it says port diameter, port length and I even linked what you needed to buy.

Cut a precise hole, wood glue that sonotube port to it, sand the opening smooth and viola you are done.

Ah got ya. Where exactly does the hole need to be?

sub and port firing back to the trunk/hatch both on the same side. Can be centered or bottom, doesnt matter look at some leave around 4-6 inches of depth for port breathing room

So the back wall should be around 5 inches from the pipe?
