Upgrade Speaker Install Questions

I'll be installing my new Pioneer TS speakers in my DC this weekend, and have a few questions.

1. I got the MDF speaker adapter plates from Mr. Marve. Do I need to paint them before installing? I know the inside of the door gets a little water inside when it rains, so that's why I'm asking. I know from my experience in construction that MDF can be like a sponge when exposed to moisture.

2. Again about the rain.... Do I need to use any type of sealant between the adapter plates and door? I see the write up sticky thread talks about using a 3M strip sealant. I have lots of silicone caulk. Will that work? Is it really neccessary at all?

3. What type of hardware do I need? I'd like to have everything in hand before I start instead of running to the store after taking the door panels off.

Thanks,

 

Uhh...

Sure, it can't hurt.

I built my own speaker spacers out of MDF so that I could put 6x9's in my rear doors. I did not use any sealant other than silicon caulk. Even then I didnt apply much, its main purpose was to create a simulated enclosure for my speaker similar to a sub box not for sealing the wood. Its not a bad idea but I dont thinks its really required. Heres what I did...
