Figure your note in the car, with the box in place. Figure 1/4 of that, put box there. However, you will find that once you've figured your quarter wave and moved your box, your 1/4 wave has changed!!! It's experimentation... just work with it, you'll get it.

If it dont fit, force it... if it breaks, it needed to be replaced anyway...
