lighter/ cigarette thing.? I did not had a stereo on my car before so i put a small mp3 speaker set taking the 12volt accessory outlet from the dash of my Saturn. However when i was checking out the rear speakers of the car i felt a shock just to touch the speaker wires. And when i tried using an ipod touch in the speakers sytem i mentioned before the back of the ipod (all metal) conducted electricity and gave me another schock pretty much anything taht i conected even the 3.5 stereo wire form the speaker system to the ipod since the tip of the cables are metalic would have a electric charge. why is this happening? can anyone tell me how to fix it or where to look for it. this is really somethig anoying. good prank to ma friends but seriously .
