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

September 1st 2022 update: After install and usage. I can say this product is average to below average. (This unit was installed at a fuse block constant 12v for 7 months and at a battery terminal and chassis ground for the remaining 8 months.) • There are times when the full volume does not function correctly. And is intermittent. • Under sudden acceleration, unit loses power or surges (either or) and discharges the siren feature randomly. • At a stop while idling in gear, the siren feature will also discharge suddenly and expose the vehicle’s position. • one of the wires attached to the potentiometer broke (no photo) and I re soldered and heat shrunk correctly all connections. •Speaker mount pinches the green wires against the speaker and shorts them out. I had to drill a hole for them the correct way. •other various fit and finish issues that aren’t worth mentioning. Overall I cannot and will not recommend this unit. It would be better to spend the extra money for a good unit. This is at most a play thing and gimmick. ——————————————————————— So far product looks great. Arrived in good shape. All knobs, buttons and physical functions work and are very tactile. The selection knob on the front of the unit doesn’t quite line up with the options (ie the yelp function). My only gripe is the dejacket on the green wire pair for the speaker unit. A few copper strands were cut on one and the other is frayed. I’m go’na have to cut and lose some length and tin it properly. I would’ve preferred them not pre-dejacketed. Instructions are clear and simple for anyone to do an install. There should be no issue on that end. Note, instructions are only in English. Will update review after install.

Better than anticipated.

Extremely loud! Love it!

Thank you

A lot of reviews said this was quiet. Its pretty loud as far as I can tell. The sirens do the job, but they have sort of a weird tone, which makes them not sound like the real deal as much. They work though and are very loud. I bought the second speaker size. UPDATE: Here I am about 3 months later, and the sound has decreased by at least 25% and the microphone is super static like every time you talk through it. Still worth the buy. It works just not perfect.

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.

Works great! The speaker is loud.

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.

Best thing I ever bought in my entire life
