Need some pro install advice/ rear sliding door speakers?

[Kevin M]

I just bought a 97dodge caravan. I have a couple cool ideas for the frontstage already but need help with one thing. Is there any way to mount speakers in the sliding doors? I looked online but my google-fu is a little lacking. I couldn't find much of anything. As long as you don't break that plane of the door panel they shouldn't interfere with the door movement right? Would you use a pair of those contacts or pins so when the door closes the speaker comes back on? I can take pictures if needed.
