SoundAlert 12V 100W Police Siren PA System Kit [120-130dB Compact Speaker] [2 x 16A Aux Switch] [Hands-Free Air Horn] [PTT Mic] [Radio Rebroadcast] Warning Emergency Siren for Vehicle Tow Truck Van RV

I ordered this as a fun little gift to use on parades or picking up family. It’s pretty loud but sounds quiet in the car. The wiring and instructions were very easy to follow. I did purchase a 40 AMP fuse to splice the power cable with. Instead of connecting to the battery directly, you can connect it to the fuse box. Along with some additional purchases that are needed for this job: heat shrink tubing, insulated wire connectors for nicer look and functionality, electrical tape, pliers, Irwin wire strippers or scissors, large and small zip ties for speaker harness and securing the wires, and some plastic saw cover that I used to put the wires in to feed through the firewall (it was easy for my old car, but it might be different in newer vehicles.Since this is my first time, I spent about 2 hours learning and doing all this. It’s best to work in a garage where you can take your time and not be bested by the heat, but be in a shade for those hot summer days.Overall, I’m happy with the purchase and the unit works as intended.

I’ve had this for about a year and it still works great. Installed on my 99 jeep and put the controller inside of the center console and the horn sits where the ABS would be (if I had it). Very loud and works great for messing with friends or communicating on the trail!

One of the most fun toys that I’ve installed on my 2008 Jeep Wrangler! Super loud, very durable, and plenty of wire length to work with!

I looked at the cheap plastic ones for $30, but after reading reviews, I decided against it due to the sound quality lacking.The quality of this unit alone makes it look very professional and the speaker is the heaviest part. It is a hunk of metal and I feel it is durable enough to withstand whatever nature hits it with. The handheld microphone is made of nice rubber and not cheap plastic like I thought it would be. The sirens and horns are very loud, but I do not plan to use them. I only bought it for the microphone and the sound is clear enough to be heard outside the car so I am satisfied.There is a lot of wires, but I only used the 2 green ones, and the red and black battery wires. The rest I do not need because I do not have any emergency lights nor want to hook it up to my cars horn.I'm sure there are louder speakers out there, but for the price, this thing is great!

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 system was easy enough to connect and the siren functions all worked great. The PA function is ok, but doesn't sound quite as good as I thought it might. Also, I tried to connect to my radio's speaker wire (followed directions) and it did not work at all....got a loud, high pitched "noise" every time the mic was keyed up (even far away). I tried to use the volume adjustable screw in the back and it broke upon trying to adjust it. So, the radio speaker function simply won't work now (but it wasn't working anyway). Otherwise, the unit is good.

Budget friendly quality siren everything works as intended ,very loud , no issues with pa system would buy again

I installed this unit on my 2019 Ranger and has been working reliably for 6 years. I don't use the siren functions since I'm not LEO but they work. The PA is great when needed to project voice outwards. Mostly, I use the cop horn function as an enhanced horn to blow away animals getting in the road or inattentive drivers. Since this is connected to my horn, the panic button on my key remote does an amazing job of frightening away Aliens during abduction attempts.
