I use something like this: AW 8 Channel Professional Powered Mixer with USB Slot DJ Power Mixing 110V 16.5"x13.2"x5.3" https://www.amazon.com/dp/B01K6QR014/ref=cm_sw_r_cp_apa_i_TAEFCbV390R2C

And this:

Rockville Dual 12" Powered Speakers, Bluetooth+Mic+Speaker Stands+Cables (RPG122K) https://www.amazon.com/dp/B00YMSWKYU/ref=cm_sw_r_cp_apa_i_4yEFCbS9K3HAM

My shows are in local VFW and AA halls. I'm sure this is not a perfect setup, but it works for me
