Total mounting depth in front doors of a P5??

[redcalimp5]

What's the deepest I can drop in a 6.5" midbass speaker in my front doors without doing any cutting/modification? I won't be using an MDF or other baffle, either, just the factory spacers that comes with the mids.

I heard a while ago that it's 3.5"....is that correct?

Go to Crutchfield.com and see what will fit. They usually have good fitment guides on audio gear.
