I've got a 1999 GMC Sierra extended cab pickup truck, and various installation requirements (mainly, excessive enclosure volume) make a typical dual 10" or 12" subwoofer installation impractical.

However, one workable solution I came up with involves a line array of six 7" woofers in a sealed enclosure. The size and shape of this enclosure would allow me to easily install it behind the rear jumpseat in the back of the cab.

Has anyone tried anything like this in a car environment?
Any benefits to doing so?
Any potential pitfalls to avoid?

Let me know what you think of this idea,

Mike
