[Using a hard material to seal hole in door or only use the deadener itself]

I have seen people sealing the holes with abs plastic, metal and other materials to really seal the door. Is the necessary or could I just trust the actually deadener itself to seal it?

Man would I love to have the money/connections to get all the speakers and amps you have, I would be constantly messing with new projects.

Keep doing all your kickass stuff and continue to be original!

[What alternator can I use?]

I have a 2004 ford explorer and I was wondering if anyone could help me figure out what alt I need. I don't need anything crazy, 170A would be fine. What model would fit my suv and would I need any modification or would it fit perfectly?
