Review on 🚨 FreeTec Amplifier Police Siren: 200W 12V Emergency Loudspeaker with 8 Tones by Jim Polacek

Done. I kept blowing up my 12v power supply trying to plug it in. Revain technical support did not help. Green is not grounded, yellow is not positive, or white is not positive. The siren/horn switch is in the reverse position. So when you turn on the siren the horn will sound, when you turn on the siren the horn will sound. The two green wires actually go to the speaker. Unfortunately it doesn't fit in the trunk of my car. So I can't give a full review. But I would give it a full 3 star rating. Be careful when you get it, you have to open it and flip the toggle switch. and make sure you connect it to a power source like I did to check the cable configuration. Otherwise, you can most likely damage the car battery.
