Review on YHAAVALE 9200E Amplifier Emergency Police Siren & Ultra Slim Metal Octagon Compact Flat Speaker, DC12V 100W Multi-Tones Wired Control with Mic Loudspeaker Electronic PA System for Police Vehicles by Kevin Williams

I absolutely love my block. I had a hard time installing it, but I'm an amateur and it was a learning experience for me. After installing and connecting the spearer, I also connected some of my LEDs to the control box to see how the controller works. It exceeded my expectations by a whole ton of crap and I would definitely recommend this siren to anyone looking for it in the market; especially if they also have hazard lights that need to be plugged in (two different switches! I have one in the front, one in the back).
