Question about Sony CDX-F7005X CD Player
We bought a used car that came with this system. It worked fine for a while; then the car was parked for a few days without being driven, and the battery wore down and we couldn't start the car. We put in a brandnew battery which also wore out after a couple of days. Someone told us that the stereo is sucking the power out of the battery, so we took out the fuse that connects the radio. Then it didn't wear down the battery any more, and we've been driving the car without the fuse, and -- without any radio. We would LOVE to get the radio (and CD) to play again -- especially since the car was given to another one of our children. We put in a new fuse, and now the car (or the radio) hums really loud after it's turned off, and after the key has been taken out of the ignition. We can press the "off" button on the radio, but that doesn't solve anything. It just hums (loudly) for a minute or so. There is no way to stop it. Of course, we're afraid it's going to wear down the battery again. What can we do to fix this? For the first few months, the car ran fine with the radio on or off. We should be able to re-create that, right? I should also mention that this car has HUGE speakers, and another fuse for the speaker system. But we haven't even put in the fuse for the speakers yet. We should still get sound through the regular speakers. Is there a certain size fuse that we need? Did we perhaps get the wrong one? Have you ever heard of anything like this? That a radio wears down a battery? Any help would be greatly appreciated!!! Angela
Put the cd player and amp on a switch

Try turning both of the amplifiers knobs down a little it should say gain or power or maybe the frequency knob like hz

If the deck is not turning off i would say it is wired incorrectly. There are two types of power inputs on the deck... One that only gives power to the radio when key is on, and one that constantly has power (to save your clock and settings) If the radio is not turning off It sounds like the two wires are connected directly to the 12volt source bypassing the key altogether.

Angela You need to keep the system rewiried or at least checked out by a professional. It sound to me like the amplifier in the back of the car is staying on this would explain the battery problems and the hum. Sometimes when wiring in systems the amplifier will use the factory speakers in the car and will amplify the sound and you create a feedback loop. ( like putting a microphone in front of a speaker) If the amplifier is not on and the power cables are unhooked and you are getting this hum through just the radio. I would suspect a faulty radio. But I am guessing from what you described you have a miss wired stereo system.
