The product is very easy to install. Just two wires. I just wanted to be able to take it off and put it on. So I just plugged in the charging cable to connect to the cigarette. Cigarette lighter / power supply 12V. It caught your voice but wasn't too loud until you put your mouth on it. then it got very loud. It was small enough to fit under the hood of my car. so it was almost invisible. overall a good product for the money.
