Question about Alpine CDA-9815 CD Player
I have an Alpine CDA-9815 installed in a 2004 Subaru with Alpine amp and Kicker box. Sometimes when I turn on the car, or go to change the radio station the sound goes out, but the power to the radio stays on. I have to take off the face, and usually blow on the connection. I have always eventually gotten it to come back on. More recently if I push on the face, either to chance the channel or volume the radio resets itself altogether. When I go to listen to a cd, it will just freeze, and I have to take the face off repeatedly to get it to reset. All of these problems are intermittent. Is it just dying?

you go to a stereo shop..(walmart autozone etc should also do) buy a mounting kit and a wire harness adapter. The wire colors on the adapter match the wire colors of most aftermarket decks. MAtch the wire colors and connect...make sure to tape wires well as if they touch you rick damage to your deck.. install the mount kit plug in your cd player and slide it in and you are good to go..

What kind of car did you install this in? Did it have a factory radio in it? If I had to take a guess I would think that there is a factory amp that you may have hooked the blue wire from the alpine deck to. If this is the case when you switch to CD the alpine deck turns off the power to the power antenna lead(blue wire) and thus your factory amp. If this is the case hook the factory amp turn on to the blue and white wire and you should be good to go.

Just a guess, I’d say who ever installed it didn’t hook up the connector behind it. But lets say they did. In most cases, the radio’s connector bundle will have a fuse. It’s a good idea to check your car’s fusebox first to see if any fuses are blown there. In either case, if you replace a blown fuse with "the right value", and it blows again, have a tech check it out. Note that if you try to get to the rear of the unit, do a little research into how the radio is accessed through the dashboard. Most car radios aren’t quickies to get at and some folks can do damage trying to get at it, but if you methodically take logical steps, you should be able to pull the radio, check the connectors, locate the fuse if it has one. Of course, there may be a wiring incompatibility, meaning, the OEM radio had it’s own specific wiring harness, the Alpine was installed, but someone didn’t get the adapter harness to fit the car. Who knows. Good luck. TekTrax

i have that same problem. when i turn the volume up, it shuts off but comes back on right away. the only thing i can think of is i'm not running the constant power directly from the positive terminal on the battery (which is what is recommended). not sure if thats the solution but im gonna try and wire it right anyway...

CLICK HERE for your owners manual in PDF format.
Please see Page 19 on how to toggle ON the AUX IN function on the radio
A KCA-121B (alpine bus to RCA) adapter is required.
AI-3NPUT (alpine bus to Female 3.5mm) adapter is required.
There is no alternate INPUT on the rear of this radio - an adapter is required... converting the changer port to an input.
