I am still up in the air as to how I am going to install the little monster. I have wanted one for a long time, now that I have one, I almost want a second one to pair up with it. So I want to start thinking about a very good SQ box with enough output for the bass to make it out of my trunk and into the cabin, which by the way the RL-p 12D2 is having some trouble with an Orion 8002 on it (just to give you and idea as to how much bass is trapped in the trunk). Anway, I looked around a decent amount and listening to Mike, I am thinking I will go ported. Even though I would love sealed but know it will not have the output I need. So according to Mikes measurements, the .4 cubes @ 30 hz looks to be about where I want to tune. But the Fs is 25.7 so I wonder the level of output that might be lost if I went with 26 hz or so. I need to take measurements first before I ask the better box builders here for a design. Just putting this up for ideas and suggestions before we start to design because this might become my show install. Plus I would get much of my trunk back if the box is nice and shallow.
