Car Police Siren 400W Signal Division PA System 940 Wireless Amplifier+2pcs Ultra Slim Metal Speaker Electronic Emergency Horn Sound System for Police Cars Fire Trucks

This PA siren sound very loud and the wireless remote control are very easy to use. You can activate the siren or PA out of the car at more that 20 ft. If install both speakers on the front grill you wont be desapointed of it. Because my car front grill don't have enoug space, I install one speaker inside motor compartiment abd the other behind car front lower grill, the suren modulw was installed under the driver seat under the a/c conducts.

The media could not be loaded. It’s very loud system, but the microphone doesn’t work. When you try to talk into the microphone, it just puts out this noise. The noise is loud but it’s just noise.

I love it I don’t like it it was easy to install and I loved how it came with the tools and everything you need to set it up and how I am using it I am a firefighter and I would love to do reviews on stuff I am willing to test things if you want me too I love it it’s loud and effective to traffic

The only reason why I bought this model was because it is wireless and because it is loud. I was able to install the unit without any difficulty. It's basically power, ground, four speaker wires, and optional light control wires. The remote control and the second steering wheel mounted optional remote control connect easily. The problem with the unit is that the sounds it makes are quite bizarre, and the names given to the sounds on the remote control do not conform with industry standards, and sometimes rotate or change position on the remote controls leaving you with unexpected sounds and a mad scramble for the power off button. As long as you are okay with this you will have a very loud, wireless unit with dependable airhorn and sometimes unexpected siren modes. No actual instructions as to operations come with the device.

My husband absolutely loves the the wireless remote and the size of the equipment. The options for different sirens are amazing and very versatile. It has only be used about a month but will update over time.

Most of the product is 5 stars. But the Microphone on the wireless controller basically does not work out the box; which I give one star. But I discovered if you take the wireless controller apart. There is a piece of foam over the mic for protection. Remove the foam and it fixes the microphone so you don't have to yell into it and it is not muffled and much loader.

Easy to install, and very loud.

Microphone is terrible and unusable, the horn button is extremely dim and weak, other than that everything is extremely loud
