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

This was installed by professional installer, Turned unit on and and it burned out. I should have expected it, low price yes but you get what you pay for.

It works great. And is loud

large profile on speaker

Not sure what they mean buy sheerness but its a pa and it works its very loud and it will kill your battery if you forget to turn it off. The horn is very effective and it gets peoples attention very well.

He’s the best and they’re worth it for you money

THIS IS THE 2ND ITEM THAT I HAVE PURCHASED FROM THIS COMPANY.. THE 2ND SIREN IS FAR BETTER THAN THE 1ST. ONE THAT I PURCHASED A COUPLE YEARS AGO.

The system was easy enough to connect and the siren functions all worked great. The PA function is ok, but doesnt sound quite as good as I thought it might. Also, I tried to connect to my radios 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 wont work now (but it wasnt working anyway). Otherwise, the unit is good.

I was soooo satisfied with the way it turned out!! all the siren noises are super loud and the the output of your voice is loud too, overall honestly wayyy louder than i anticipated. there was only a small problem that i encountered- there was no fuse grabber from the red output to the battery. had to go out of my way and spend only a few extra dollars, not to big of a deal. I also had to spend more money for wire extensions and crimpers but that is only because i installed it into a truck and the battery was on the opposite side of the firewall. I also recommend that you have someone with experience and knowledge in mechanics because the wiring can be a little bit tricky for those who are inexperienced in wire install, especially in a car or truck. highly recommend you get a friend in general to help with install as well. i just hope it lasts...

Installed in about 30 min. SUPER easy install and I’m not even that familiar with electrical. It’s pretty simple to be honest. I was skeptical about buying this because the price was so cheap. Well lemme tell ya! ITS LOUD! I have the speaker installed underneath my F150 facing the ground (to help with the db’s) This is beyond loud enough for what I’ll be using it for! Obviously the sirens won’t be getting used but the horn/radio PA system are great!

Its really loud and I like the functions but had it installed for about a month and the fried, not sure what happened.
