First: This product was given 4 stars because I believe that there shoukd be as much information available about a product so that the customer can make an informed decision. Not dling so risks the product being passed by.In this case, this item is a wireless PA/Siren/Horn with 18 sounds. Maybe its asking too much to know what those sounds actually sound like! But there is nothing of the sort provided and nothing avsilable through the seller (I checked!).I did, however, find pretty much the identicsl item by a different name and through a different website. They actually DID provide the sounds the unit makes. To find the item was no easy task and took a bit of time. Had I not found it, I would not have bought this item.It comes in two boxes and includes the basics. The manual is pretty skimpy - but the wiring diagram proved helpful. You will need exrra wire in most cases.Connecting this item is pretty simple though time consuming. - Mount the spaaker somewhere nearest the grill for max loudness. - Connect the speaker to the wiring harness provided using the 2 green wires. - Connect the red and black wires of the harness to the car battery. - Plug in the harness to the host amp/brains. That should be placed inside the car to protect against the elements. - If you have optional lighting (up to 2 sets) connect to the other wiring harness and the harness to the amp/brains. - Turn the power of the amp/brains on. - After charging the remote using the charger/cord provided you are ready to go.Using this product requires the wireless remote. The top 2 rows are siren sounds. You press one and the sound starts. Press the same button again or the sound off button, the last button on the right of the 3rd row. Pressing the button to the left on the last row will change the sound for that key. Another words each of the top 2 rows of buttons can make 2 sounds each.The 4th row has 2 buttons that are horn sounds. While pressed the horn sounds. Release the button and it stops.
