I really like the sound of them. They get pretty dang loud and sound good doing it. I think I'm the first person to make videos of these subs which is pretty cool. I bought them as soon as I seen them.
But I can't get any real car carpet in my town, so I had to get something close to it. I really wanted the carpet that you usually use though. Can't find that stuff anywhere except online. The amp rack and sub box carpet are the same by the way.
Its a brand new box I just made. Both subs are in the same airspace. Its 1.68cuft tuned to 40.347hz. Port is 3" wide. This box sounds way louder and better then my other boxes.
I was thinking of putting more power to them. But I already have the amp I bought at the same time as these subs. I was thinking of getting another Jbl Gto1201.1 but My subs are dual 2ohm. So I won't get full power. I was going to get two more of these subs. So I have four in the trunk but I think I'll get some Fatmat instead.
