Enclosure for Type R's

[JP-12]

How would I go about finding dimensions? I'm trying to build a box for 2 type R's in my focus. Don't really want to go with a prefab,

Post amp and vehicle exact models, model of the subs (starts with SWR) and max dims for a box that can go fit in it's way inside the vehicle.

[JP-12]

Amp: alpine MRX-M240

Subs: SWR-12D4

Trunk space:

H: 20"

W: 39"

D: 29"

But I think I can only fit about a 15" height unless I build it straight into the trunk

It can be done like this, power: to subs rated, amp subsonic filter to 28Hz, build a cardboard dummy box to test fit before cutting any wood:

Thanks so much!

Love that everyone is so helpful on here! It's awesome!

Been tryin to learn more lately so hopefully I can help out someday! Haha

What's best wood to use?

[JP-12]

Oh and am I supposed to put those cylinders in it?

[Joe X]

The cross braces are optional, if you want to do them those are 1 1/4" wooden dowel rods, for wood use 3/4" MDF, cost effective and does the job right.

I am currently building a box for two 15" for somebody right now, 34hz is a really high tuning for this line of subs.

One more question. What about the corner pieces?

[Joe X]

45s if you want to do them are 2 1/2" wide except the one inside the port, here's how to do it:

The width of the port at the corner must be the same as the rest of the port.
