Audio Systems: need help, loose connection, passenger seat

Question
im running my cd player and when i start to drive it cuts out the power and comes back on when it wants to do u know what the problem could be? I checked the power and the ground and that is all set up the right way and it works

Answer
sorry it took me so long,  I've been pondering this that's all.  sounds mostly like a loose connection.  if I were you, I'd get a meter (18 bucks at walmart) pull the cd player out and test the wires for power going to it, you should find a constant positive, negative, and one that is only positive when the key is in the "on" and "run" or "acc" positions.  once you find them and they seem to be steady etc. have someone ride in the passenger seat with you that knows how to test these wires (basically just hold the meter leads on the right wires) and see if power drops or goes completely out while you're driving.  you may just have to run new wires or something depending on what you find.
Good luck!  let me know if I can be of any more help.
