SoundAlert 12V 100W Police Siren PA System [Slim Speaker] [118-124dB] [Handheld Microphone] [Hands-Free] [2 x 16A Switches] Warning Emergency Siren for Vehicles Truck UTV ATV Car POV

Decent loudness with all sirens and horn. PA lacks the same punch as the rest tho at the same volume setting. But it is usable. Maybe the traditional horn loud speaker version maybe louder than this slimline speaker. Its supposed to be slightly louder. And $30 more. I installed this in a 2016 Tahoe and passing the wires from inside the truck to the engine bay was a a nightmare. There is only one passage and that is where the upfit for the police package goes. Otherwise the inside cowling has 3 separate walls to pass thru making it impossible. Search YouTube for passage location videos for your application if you install in late model vehicle. My Tahoe has a plug in passage hole in door body pillar right behind top drivers door hinge. Then passes thru inner fender well to engine bay. Use a stiff but flexible wire to work thru passage into under dash area. Make sure to connect to power with ignition on only. Otherwise a straight battery connection may kill your battery overnight if you leave the power switch on, making you late for work. Ask me how I know!

Oh man, I love this thing. Its ridiculously loud and has lots of options with various siren tones, the horn, and the radio repeat. There is a lot of empty space in the case, and could definitely be smaller and easier to mount than it is. I elected to stick it under my seat. Do yourself a favor and do a couple of light coats of black spray paint on the speaker before you put it behind your grill. Also, the instructions are pretty vague, in particular how to hook up the horn relay and radio audio input. I have one of the horn relay wires wired up to see ground, and havent figured out the radio audio part.

Its loud worth the money. Used it for off-roading. Will purchase again in the future

It’s loud, but the siren functions don’t sound that good. It sounds like the siren on a toy car. The PA system does work good though so if that’s all you want it for then this is good for you. All the sirens are weird sounding, the siren horn sounds good unless you hold it for too long, and the regular police buzzer horn sounds good. Well worth the money if they fix the dollar store siren sounds, but at the moment if you’re looking for a siren that sounds good, look elsewhere

meets all my needs

Works amazing

Works well. Louder than expected. Only downfall was order came without the wiring harness. Had to build my own for it.

Me and a buddy both have one it’s really fun to play with just don’t do anything stupid with it to get in trouble if you use it as a toy. Really good quality and sound. Really fun to scare your buddies walking in front of you.

Doing caroling around the town this year!

Excellent quality
