    Hello, I'm a car mechanic and have fairly basic knowledge of car electronics, BUT, I'm a complete novice with audio. Would I need an adapter to connect this to my cars existing audio system? Thanks!


    Thanks for your question, if your stereo has no RCA inputs you can use an RCA Converter as shown, to take a signal from your speakers.
