2004 altima - door speaker resize

[ikpunjabi2k]

I have a 2004 Altima with 5.25" stock speakers in the front doors. I have 6.5" polk audio speakers from a previous car. Is it easy to resize the hole to fit the bigger speakers and how would I go about doing it? I want to make sure nothing starts rattling after the install.

Thanks for any advice

Hmmm. Well, you could always cut the hole larger to fit the 6.5" Polks. If the factory speakers are in plastic "pods" behind the door panel, you could simply remove those and create a pod out of wood that fits your 6.5's.
