Power Package? Sorry, not familiar, whats that?
At crutchfield.com you can enter your vehicle and they'll tell you which speakers will fit or not.
With the extended cab selected, there's only a few available, and it seems that they all have a mounting depth of under 2". Conversely, when I select Regular Cab, everything's available.
I really don't see there being a huge difference in the door depth between the two models, so I'm going to try my luck with normal depth speakers....I can always return them
