I'm looking to sell or trade my Alpine CDM -7871 cd player.I don't have all the specs right now but I do know that this deck is rated at 45 watts by 4 channels,will control a cd changer,has a motorized multi angle detachable face,and three sets of pre amp outputs including a 4 volt subwoofer output.The unit overall is in pretty good shape.The only bad thing I can say about the appearance is that the lettering is wearing off a couple of the buttons. I will post pics of the unit as soon as my wife gets home with the digital camera. If you need any further info feel free to message me or you can also refer to the owners manual in pdf form on the alpine website.I would like to get 100 dollars shipped or trade for a nice 12 or 15 inch sub or maybe even an amp depending on what you have.
