I want to build a 4th order bandpass for my trunk this weekend, and use my 4 RD Sonance 12s". I want the port to be going through the ski port. I figured this is the best way to get all the bass into the cab since I don't roll with my backseats down.
The ski port does NOT set flush with the floor of the trunk so I'm guessing I will need to slant the port to some degree. I DO NOT want the port going THROUGH the ski hole. I want it to set a couple of inches away from it.
I want this to have a flat response, but get low as well.
My max dimensions are as follows:
15 H x 30 W x 33 L
Ski port dimensions are : 6.5" wide x 10.5" tall
Here is what my car looks like in the trunk and backseat:
