No.

This is a subjective matter. You may be happy with the single 12 and a
200 wrms amp, or you may be completely unsatisfied. Any decent shop will
be able to do an in-car demo, where you pull up to the bay, they drop a
box with speakers in your truck, and play it off an amp (either from one
of the employees cars, or one hooked up to a power supply in the shop).

It'll also depend on your listening tastes and budget. Asking other
people for their opinions is basically asking other people to make your
choices for you, and I guarantee you'll rarely be happy taking what
other people think you should have.
