What amp do I need to power 4 of these to their max?

700 to 1200 watts amp with a subwoofer min 800 to 1000 watts to get good sound

Are they water resistant speakers?

While I'm not 100% sure I'm going to say no.. they are designed to be inside of a car protected for water/rain.

What's the cut out size I need for the speaker

Maybe a little trim cause the magnet is big
