My local car audio gurus (read: shop owners) are too busy to answer these kinds of questions. Away we go...
If YOU were ME.
You own a pair of each of the following:
Alpine Type-R 5.25" Component speakers
Alpine Type-R 6.50" Component speakers
Alpine Type-R 6x9 Coaxial speakers
Alpine Type-R 12" subwoofers
Amplifiers to power all of them.

How do you arrange this setup in a Ford Contour?
