How did you get the p321's to fit?? I bought those and even with shaving down the grill from the truck they were too "tall". Did you cut off the plastic cover from the speaker? Just curious.

Refer to my post in the link above. I had to modify the OEM brackets and reused it. I have pictures that may give u an idea. Give me about a week and I can take new pictures of the dismounted speakers to give you a better idea of what I did. I need to add bass blockers of a different frequency. The passenger side took some special fitment but its possible.
