[2 SA-12's CT Sounds 1400.1]

OK so this box I could fit in my car but I would be able to get the recommended 4 1/2 inches of space for the port. Can I take some off the depth and add it to the height. How do I figure out the dimensions for the internal port. That would also change the port length also ugh.. can I get some help please?

I have found its 28 cube ft of space but I'm looking for actual dimensions

You can see where the box is tearing apart from my old Amp lol oopps

It's a prefab box I just took a picture but can't figure out how to upload it...

Just a basic vented box for 2 12s im doing some research on boxes right now i believe that is the start of it

Recommended Ported Box: 2.0ft^3 (Tune to 35Hz, yields F3 of 28Hz)

What the hell does yields F3 of 28Hz mean.

I have this setup

2 SA-12's 4 ohm CT Sounds 1400.1

Currently on 4g wire I haven't had the $$ to upgrade yet.

My box is vented nothing special

Up until yesterday I was running an Alpine 600.1 and my system hit hard so I wanted to upgrade my amp found a CT Sounds I wired my SA's to 1 ohm and now it sounds like I'm using a sealed box in theory I doubled my power but I'm not feeling it.

.. What gives?
