A WHILE BACK I PURCHASED AN ALPINE CDA-7894 AND WHENEVER I HOOKED IT UP THERE WAS NO MUSIC COMING OUT OF THE SPEAKERS OR PRE OUTS WHEN AN AMP WAS HOOKED UP, JUST CRACKLING NOISES. I TOOK IT TO AN AUDIO SHOP AND THEY SAID THAT IT SOUNDED LIKE THE AUDIO CHIP WAS BAD. THEY REPLACED IT AND STILL NO MUSIC. THEY SAID IT COUILD BE FIXED BUT THEY DID NOT HAVE THE PART NOR DID THEY TELL ME WHAT WAS THE PROBLEM. PLEASE HELP!
Re: CDA-7894 ALPINE CD CAR STEREO NO SOUND JUST POPS
The head unit needs to have the power supply of the head unit turned off so your external amp can be the power item. Its detailed in the manual but here's how. Hold the setup button for 3+ seconds (it's the small button to the left of the 1) use the up & down button (left & right arrows) to scroll through the option until you get to "PWR-IC". press the band button to toggle it on & off. It should be set to off so your external amp does the work.

Check the fuses. There's one in your car's fuse panel (usually in the footwell be the hinges of the car door) & one on the back of the head unit. While you have the head unit out checking the fuse, ensure that the power wire is still connected securely and the ground wire has a firm, clean connection to the sub dash (clean metal, no paint). If this doesn't solve the problem, the unit may well have gone belly up. You will need a new one if that's the case. If you purchase a new one, stay away from Dual. It's garbage. I know they're super affordable, but you get what you pay for with that kind of stuff. Pioneer makes really good units and there priced reasonably too. Just a suggestion... Good luck!
You have a problem with the phasing of your speakers. This will happen if on or more of the speakers are installed incorrectly. To solve this, you must check the speakers and find which one of them does not have the positive and negative connected to where it should be. When connecting speakers it is crucial that the speakers (positive and negative terminals) are all connected to the corresponding (positive and negative) speaker outputs of your head unit.
Now you can enjoy your sound again.
Hi my names Josh i was reading some info on your unit. Thats a very nice unit was made in 03 and had alot of really nice features on it however if your looking for fan that unit was not equiped with one that slot in the back is not actually a fan but part of back plate design of the unit.
You can purchase the KCA-420i and connect it to to the ai-net port behind the headunit. This will allow you to send signal from your ipod to your alpine headunit while still retaining your operating functions to the ipod. Can be purchased for about 10 bucks on ebay.
ok when you look at the front of your system there is a button that has a (F) on it press and hold tell stuff comes on the screen then just keep pressing it tell you get to AUX off you should get it from there hope this helps
