I had a similar issue in one of my older cars and my passenger mid got damaged. I ended up using some rubber and plastic material to build a baffle around it to keep water off of the next one and had no problems with water after that.
All of those brands are owned/made by one company (Directed). Viper/Clifford are their top tier alarm and remote start entities. It really depends on the features you want. If you go to directed.com you can select all in one systems, and add other features to it.
