I've been looking to replace my stock 4x6s up front but had a question on getting them out. The grills easily lifted out put it doesn't look like there is enough room to get the speakers out, or get a new, bigger one in. So does the dash need to come out? If so, how is this done?

It helps to lift the dash cover off yes, but stick with 4x6'*...that top dash is easy to take off..

You know how to right?

No, how does the dash come off? I didn't see any screws from a quick glance.

The first half may help
