Steve your right. I wouldn't have even thought about it.
Let me add more to the mix. Aftermarket speaker, concert sound, inside door painted, bottom inside door probably coated with something heavy. Now we're talking two pounds.
I'm already prepared to buy lighter speakers. I've always been paranoid with my stock doors. What I'm worried about most is where the hinge connects to the body.
The good thing about replacing the doors is that when I feel like it I can restore the old doors and sell em. I don't have time to get into that project right now as I'd make them as perfect as possible, like new doors.
