SoundAlert 100W Emergency Police Siren Kit [118-124dB Slim Speaker] [2 x 16A Switch Control] [Hands-Free Air Horn] [PTT Mic] [Radio Rebroadcast] Warning PA System for Emergency Vehicle Trucks Cars

Install was easy and all hardware minus the bolts to mount the speaker. Its not as loud as other ones out there but its noticeable. When the mic is connected the speaker clicks and the siren randomly goes off. I ordered a replacement and it does the same thing. So I only plug in the mic if I need the PA but you have to unplug it if you want to leave the unit on.

The shoulder microphone BARELY picks up any voice input. Aside from that the alarms & wails sound good.

This is the version 2 unit I had version 1 as well it works perfectly very loud, the version 2 has a much better built microphone unit and it is detachable

Very fun and loud

I was a bit skeptical when purchasing this as I have never heard of this brand but I bought it anyway to give it a try. I installed it on my car and everything was pretty straight forward but my vehicle made it more difficult than it should have been. This product brings all the wires you need, siren, siren selector box, hardware, the removable PA microphone, and 2 solid brackets for both the siren box and the siren itself. Once installed, the sounds were extremely loud. Way louder than I imagined this product to sound. The large selection of different siren modes and the loud and clear PA system all work as advertised. As for waterproofing of the siren, we have had about 2 weeks of constant downpours and I have driven consistently every single one of these days yet I have not encountered any issues for the waterproofing of the siren. As for my favorite features of the this product, it would have to be the wide selection of siren tones along with the removable microphone which helps if it’s in the way. Overall, I am very satisfied with my purchase and I recommend this product to anyone that is debating this over anything else in a similar price range.

the quality of the product is better than expected. built just like the real ones such as Whelen brand. could be louder but plenty loud for having fun.

love it, love the horn

Works great is very loud and is clear when you speak out of it. Siren and horn work great also have used it a few times already!!

Great Product. 2 years later still works perfectly. Thanks Super satisfied customer

Highly recommended to all buyers who want to equip the patrol PA system into his / her bike or car. For me, i installed it into my used Patrol motorbike (formerly owned by Police Department in Malaysia)
