wanting to get these and throw them into a prefab box

the box has a slot port in the middle but im unsure how to find out what its tuned to if anything.

each compartment is well within the recomended cf i think.

this is the box

didnt see the cubic feet listen when i originally bought it but here is one identical

now how would i find out what the port is tuned to

[MACnonsence6]

^ He said it, prefab is horrible!

id think throwing the woofers at a box would damage them

if you want to get the best out of them build a box

if you dont care then keep on tossing them woofers

Yea prefab is sloppy shit. Spend one day and makesomething nice that your going to like.... it only cost like 30 for mdf glue and some screws

[C-Fizzy]

prefab boxes are usually tuned way too high, and if you try to play a note lower than what the box is tuned too, say goodbye woofers. Spend the time, make a box.

id like to make my own but idk how to calculate a port or how to figure out internal cubes and those little things on here where u put in numbers i dont understand how to use it also if i made one id want it to be the same size and everything becouse that box fits in my car perfect and does not move no matter how crazy i drive only thing id wana do is maybe port on the side but again idk how to calculate it and idk if that would be to much cubes per sub

Prefabs are tuned to 45hZ usually. There's nothing wrong with running one in a trunk since the minimal air space will help with cone control, but not enough to stop them from blowing from abuse.

Honestly, if you want to save money, people will help you design it and it's much cheaper for one sheet of wood than a prefab box. But if you really don't want to venture there, then do it. There's nothing wrong with it.
