Hey all,

I just put in a new Alpine CDA-9856 head unit into my truck. The radio will work and play fine, but the CD player isn't working correctly. The unit will read the CD and play it, but no sound comes out of the speakers. I don't think I wired anything wrong, because the radio plays from all four speakers fine. I connected the wires by stripping each from the head unit and wire harness, twisting them, and sealing them with electrical tape (kinda amateur, I know, but I think it worked). I've been messing around with the options on the head unit with no success. Anyone here own this head unit and/or experienced this problem? Any help would be appreciated! Oh yea, btw, I have a 99 Ram 1500 Sport 318 4x4 QC, not Infinity.

Thanks,

I don't have this radio, but per their faq, it's probably wired wrong.




Hope that helps.

 

Thanks for the reply fiveliterbtr.

Unfortunately, that's not the problem. Both wires are matched, solid blue to solid blue, striped blue to striped blue. Also, on my way to school today, something started smoking from inside the dash. It was leaking out of the middle air vents. It didn't smell like smoke, it I turned the A/C on to max and blew all the smoke and some fine white particles. Turned it off, and the smoke diminished. My wires were in the air channels behind the radio, could that be the cause of this? Could this be from the head unit, maybe a bad ground? The wiring harness I bought had a wire for a ground, but that one was a larger gauge than the one from the unit. Any more advise or help?

Thanks,

Well, with the smoke and all, I'd be taknig the radio out and having a look.

Going from a smaller ground wire to a larger one isn't gonna cause a problem like this...guessing that something has rubbed thru near a blend door or something...or some of your electrical tape came loose when putting the radio in the dash...you need to pull it out.

As for the miswiring, I understand that you have blue/blue and blue-white/blue-white connected...what it's suggesting is that your using the blue ant. wire as an external turn-on instead of the blue-white...can't suggest anything else other than pulling the radio and double-checking.

 

fiveliterbtr, you are the man!

I switched the blue wires up, and now everything works perfectly. Smoke is gone, might have just been from the miswiring. I couldn't be happier. To anyone considering buying this head unit, I highly recommend it. Just make sure to switch those blue wires!

Thanks again!

No really, Alpine is the man...apparently it's enough of an issue with them to have it in the faq's...I've only really dealt with Kenwood, JVC, and Pioneer on a regular basis and have never had a wiring issue...hopefully, they'll choose a different color in the future to avoid this.

Glad it's fixed

 

Usually once you let the smoke out, it won't fit back in. Glad it still worked. Did anything look burnt.

 

 

Ya, that's what I was worried about at first. Spending $200 on a new cd player only to fry it! Next time I'll have to be more careful. Chopper, nothing looked burnt, I have no idea where the smoke came from. Just went on a 3 hour trip yesterday, and no smoke, everything worked perfectly. I guess I'm just lucky.
