What model car do you have???
As for kick panels, pre-fabbed ones made by Q forms are "so-so" from what I hear and they cost like $150-200.
Custom made ones are the way to go, but unless you know how to make them, they are real expensive...
For most of us non-competeing car audio guys, stock location is fine.:thumbup: So in the door and sail pail (plastic piece opposite the mirrors).
