VEVOR Mophorn 200W Car Warning Alarm Vehicle 7 Sound Loud Warning Alarm Kit MIC System Emergency Fire Siren PA Speaker

The good: The tones are the correct universal tones and the horn is the correct horn (no Mickey Mouse crap) and they are clear. I got it for the siren function and that works well.The bad: The wiring diagram is not so good. Here is how you instal it (USA)... Red is 12V positive (battery) , Black is 12V negative (ground), White is switch #1 12V positive to light #1, Yellow is switch #2 12V positive to light #2, Note: It is wise to run the white & yellow to relays that run the lights so that you don't "over draw" the amp capacity of the switches, Greens go to the speaker, Note: Insulate all splices and connections to speaker prior to powering up the unit, grounding a speaker wire under power can damage the unit.The ugly: My mic came in damaged, rattled right out of the box, so the mic/pa ain't working. I've seen this same issue on units that cost twice as much. The rest of the amp system works well so I'm thinking that a new mic will fix that.I got it for the siren (not the PA) anyway and that works really well, so for the money you can't beat it

Installation was easy and sounds pretty good.

I’m a strong believer in “you get what you pay for”. I bought this for the airhorns, but oh man is it a good system. Only complaint I have is the complete lack of instructions. Horrible translation and little to no information whatsoever makes this difficult for beginners with little to no electrician knowledge. The speaker plastic was cracked on arrival, but that was due to the shipping. It didn’t effect the loudness of the system whatsoever. Just as a bit of help, the two green wires go to the speaker. The optional yellow and white go to any devices you would like to use the systems integrated switches with. I would highly recommend replacing the wires from the outer harness with your own, just due to how flimsy and small the current ones are.

Ordered 2 of these. They are extremely loud and will get the attention you are looking for. The one speaker cone did arrive broken but besides that see how long it will last!

This product was very easy to install with easy to read directions! I would agree with one comment that the wires are not long enough leading to the battery and depending on where you install the horn the two green wires going to the horn may not be long enough however anyone and everyone should know how to splice wires. Just installed today so it will be interesting to see long term how this product performs.
