You may have a bad speaker, if you can, try disconnecting the speakers one at a time and see if it cures the problem.

The volume control in this unit is most likely an Encoder and these have a nasty habit of getting dirty inside and false reading back to the computer that runs the receiver. In the past , I've had good results opening up the units and spraying what's called De-Oxit D5 into that volume control and rotating the thing a couple dozen times. . De-Oxit can be found on Amazon or Radio Shack

The cause of the problem is that the switch of your tv is dirty when cleaning it you must be familiar to the unit and the parts you will remove to prevent any damage you can use a contact cleaner, when applying a contact cleaner you must only spray it to the switch. Consult a expert technician to do it for you actual.

No sound


First check if your nuvi is not on mute by touching the button next to the volume that reads mute, then you try to increase the volume. To increase the volume:
  1. from the main menu,
  2. Touch the volume,
  3. Then you adjust it with the left and right direction button to increase it or reduce it.
If that does not solve the problem, then you need to reset the nuvi, by holding the power button for about 15 seconds. It will restart itself. Or you can remove the battery and install it back in. If that does not solve the problem, then it is an internal problem.

My alpine 9965E LCD display keeps on turning to black after a few seconds, but the head unit works. If i increase the volume, go to the next track, the LCD display pops out again


you have turned on the "black-out" feature to get it back look for a little button over the volume knob with either "dispay" or "blackout" on it. Press and hold it and you will hear a beep to let you know you changed it. Why Alpine put that feature in the head units is to confuse and comfound drivers is my guess.

Volume increases by itself


This could be a sticky button or a bad key controller! The key controller is the button board, this stream the commands to the main board (main unit). not to hard to replace, if your somewhat handy! But will require the case (back panel) to be removed. Good luck, hope this is helpful!

Volume increases on its own intermittently


When the volume increased did the display show it doing so as if someone was turning the knob?  I mean did the volume go from like level 15 to 30 or did the unit's level stay constant while the audio volume increased?
Were you alone or sharing the room with a jokester who has a universal remote?
Does this problem occur when the batteries are removed from your remote?
Are you sure the 'volume up' button on the unit itself is disengaging properly after being pressed?

I have an Alpine CDA-9815 head unit installed in a 2002 Dodge Dakota. I currently have a 12" DVC sub bridged at 4 Ohms. My head unit's volume goes up to 35. When i turn in past 24-25, the head unit...


It sounds like the sub woofer amplifier is pulling down the voltage level in the truck when it starts to get really loud. It may be the voltage regulator which is probably part of the alternator, or the alternator is not capable of supplying the needed current for the amplifier. If the voltage level drops below a certain level, the radio will see it as if the battery is disconnected. It requires a voltage level of around at least 10 volts to stay turned on. When an amplifier is playing loud, it draws a lot of current. If the current supply does not increase, it lowers the voltage level to compensate and get the current it needs to play at the level the head unit is pushing it to. As the voltage level goes down, the current increases when the voltage is dropping due to increased demand. You could check this with a voltage meter and monitor the level right at the battery and have somebody turn the volume up on the head unit slowly as you monitor the voltage level. The normal operating voltage of a car while the engine is running is about 14.4 volts. It should not drop much at all, no matter how loud the amplifier is playing. if it does drop, you have a problem with the trucks regulator or alternator.

I hope this helps, if you need more assistance let me know.

Volume fluctuates???


-Your head unit has a sound monitor that increases volume to compensate for road noise. -Your amp isn't receiving enough power.
