However, there are many options when it comes to wireless microphones. I have done a complete article on wireless vocal mics, lapel mics, and headset mics. I suggest you read that article and decide which mic system or systems would be the best for your situation.
Again I am going to recommend a wireless monitoring system. However, if you do not want to use wireless in-ear monitors, then I suggest the Kustom KPC4P Powered Monitor Speaker. They are a pretty standard powered floor monitor. You can use 1 or more to give sound to your musicians.
However, if you want to go light and wireless, I suggest you look into wireless in-ear monitors like the ones I have recommended in this article. This system is not only compact, which is essential for a mobile church, but give the most control to your musicians, once again shortening your set up time.
In a traditional sound system, you have a power amp that gives the power to make the speakers work. In a portable system, I recommend that you use powered speakers and have one less component to set up. Remember, fewer cables and fewer parts mean less work for your volunteers.
Once again I am going to suggest a couple of powered speakers for you to consider. They are not the cheapest, but they are from reputable brands in the pro-sound market.
