ok so i want to build/ play around with a bandpass box for the g\f's car. i want to do a 4th order( the one with the sealed box going on to a loading wall) i think its called a 4th order. so what i am asking is what are some guide lines to going about this? also is it worth doing in a car as a removeable box?

thanks justin

4th orders take alot of trail and error because every car is different. usually the sealed partition is around the manufacture specs, and the ported partition is something you have to play with. start with alot of port area and a high tuning, and go from there.

I would use 2x4's as temporary port walls because they are easy to remove
