I need to turn the subwoofer volume up

Get one of these: http://www.crutchfield.com/p_500CDA9883/Alpine-CDA-9883.html?tp=5684&tab=other_items#iPod Adapters

Check for blown fuses behind the deck and under the hood, sometimes by the battery, you may get lucky but you could have smoked the unit, and would not know anything unless you send it in to get fixed. Replacing the unit could be the answer Alpine CDA-9883 CD Player

Check for a fuse in the back of the radio, and the one in the fuse panel

try detaching the "face" and there should be a little button that you can only push in with some kid of really thin stick,maybe a pin that will reset the cd player and hopefully work

your ipod might be too new,and your cd player too old the alpine cda 9883 is a 2007 model what kind of ipod do you have,if uyou have an older ipod and got the new itunes9 then try downloading an older version of itunes from itunes.com .....good luck

There is a site which i have posted below that stocks that trim ring for your Alpine model. Hope this helps you out.

It sounds like it was hooked up incorrectly, and possibly a wire is loose... i would have it checked out professionally before something happens. The other possibility is that it is overheating and is going into "protect mode"... as i said... i would get it looked at professionally.

press and hold the menu button until display changes then turnthe the volume button until mx shows in the display then press the tuner button to turn on that feature

Your amp is not turning on - what you should do is connect the "blue/white - remote turn-on lead" to whatever wire you have the "blue - power antenna" output from the Alpine connected to now. That should solve your problem.

one of your seakers is faulty unit into protection mode
