My current box is 6.5 ft^3 tuned to 32 with ~80 sqin. of port, sub up port forward firing towards the hatch in my pathfinder. The response from 33hz and down SUCKS, so I'm going to be building a large low tuned 4th order for it. My question is, is a lot of the crappy response from my box, or is there a possibility that my car just really doesn't like lows?
