Default Plastic Door Grill Affecting Speaker Performance?

I have a set of 6.5" HAT Imagines active. My mids are in the stock door location with no mods besides a mdf baffle so they would fit. The grill is the typical concave plastic circle with holes all over it. The plastic is rather thick and I was wondering if this would affect the sound much. I've been considering either drilling the holes larger or removing the grill altogether and adding the wire mesh grill that came with the Imagines. Although, I'm a little hesitant to mod the doors since I don't plan on having this car forever.

I've listened to the speakers with the doors on and off but honestly I'm not sure if I can tell a difference. You see, when the door panels are on, my seats are in the car as well; when they are off my seats were also out, and I was sitting on the floor rather than my seat. I could tell a difference but it may have been because I was sitting at a different location. Regardless, they sound amazing how they are right now but if I can get some extra performance out of them I'd like that.

Well crap lol. I'm going home soon to work on my car and one part of the project is beefing up the doors so maybe I'll try a few things and report back... I'd still like to hear from someone else though lol

you would get extra performance, add up all those little holes into a large space and the plastic covers about half the speakers. well, at least in my car they do.
doing a mesh grille is the same but the amount of holes to steel would change.
cloth would be a better option. anything you add in front of a speaker will always be detrimental towards sound quality.

but if you say you dont hear a difference leave it as is.

This is my assumption as of right now. When I get home I'll pop off my door panels, see if there's a difference, and go from there.

It's going to depend on the passband of the speaker. Grilles and covers will create diffraction, but it's mostly realized in the higher range of frequencies. You won't notice much of a difference with mids in doors playing through door panels, but you'd notice a difference if your tweeter was playing through it.
