I have only done a few installs in the cab of trucks. most of them small sealed enclosures that go under the seats. This summer i plan to run 2 FiQ15s in an extended cab truck. With the back seats out i have 17.5 cubes to work with under the window line. What would be the best sub/port placement for the box.
