Hi there I have alpine cda 9856 cd player and it turns on and does every normal however it won't output and sound on either radio or cd. I have checked for any bad connections and can't seem t

Did you make sure you have no shorted or grounded speakers or speaker wires? Make sure you don't have a bad speaker also. If everything checks out, you may have a bad internal output ic.

I have a Alpine CDA 7892 CD head unit I just installed and the radio works perfect but when I play a cd it sounds very muffled and I can hear bass only. Is the unit bad?

If the sound is coming out clearly with the radio on, then there is a problem with the cd drive or its connections. If your stereo has aux. inputs, you could run an mp3 player until your ready to replace it.

How can I get my ipod to work on the Alpine CDA-7892?

Ai-NET/RCA Interface cable (KCA-121B)
Converts the changer port to RCAs... then an RCA to female 3.5mm female adapter.
Or an FM Modulator.

I believe you need the Alpine KCA-410C - Ai-Net multi-changer/versatile link adapter before you can input from an external source directly.

Cd stuck, discread on display

If you can access the in-line fuse on the constant 12+ volt lead that powers the units memory. Remove that fuse and wait 5 min. then replace it. This should reset the unit, allowing you to eject the CD.
Note: If the anti-theft code has been enabled, you will need to input that code in order to operate the unit.
If the CD still does not eject, it may be jammed/binded up. thus requiring dis-assembly.
Good luck...

Auxilary RCA inputs have no volume control

Your problem stems from the fact that the CDA-7892 is not equipped with an RCA aux-input jack. If you're plugged into RCA connectors at the back of the head unit, they're outputs, not inputs. The sound you hear is just feeding back through the outputs and into the head unit's amplifier. If you want to play your iPod through this head unit, you need to purchase either the auxiliary input adapter (KCA-121B) or iPod adapter (KCA-420i).

Alpine cda-7892 Head unit overheating

Certainly, the output IC might need to be replaced, also check to see if there is a factory amp somewhere in the car. Additionally, double-checking the wiring is a must. How long does it take for the unit to heat up?
