Stays on even if HU (CDA-9833) is off

I have been having dead battery syndrome since installing the SIR-ALP1. I have it as well as a CD changer installed via Ai-NET cable to a CDA-9833 head unit. The problem is that even if the head unit is turned off, the SIR stays on. When I remove the Ai-NET cable, the SIR unit turns off. The system without the SIR does not kill the battery. So apparently the Ai-NET connection to the changer doesn't keep it on all the time as it seems to be doing with the SIR. One thing to note, the HU is hard wired to the battery. Both the ignition as well as the main power wire are wired to the battery so no key is required to power up the unit. I don't know if changing the red wire to a switched power source would make a difference. Thank you for any assistance you can provide. Pete

You could add a relay to power the sirius and you could use the remote turn on lead to control it.

Re: Stays on even if HU (CDA-9833) is off

It is possible that the SIR unit stays powered as long as the red wire is powered, since it is normally connected to a switched source. To test this, disconnect the red wire or move it to a switched source (you could even add a switch on the wire and flip it manually). If the battery stays healthy after that, then the red wire being constantly powered is the problem. Otherwise, it is possible there is a problem with the Ai-NET cable connected to the SIR unit.

I have my cd changer (alpine) plugged into the input port via ai net cable and I have the output going to the alpine radio (cda 9886) via ai net cable. When I hit the source button everything comes up but...

One thing to verify is that the Ai-Net switch at the bottom of the radio is set to Norm and not the EQ position. And also gray Ai-Net connectors are for audio input and the black Ai-Net connectors are for audio output. It sounds like you have everything connected correctly and at least the Sirius is coming up. And I assume that the CD changer works when connected directly to the reciever so you know that it is working. I would suspect that there might be a problem with the Sirius reciever not allowing the communication signal to connect to the Alpine deck and in that case you would need to get a new reciever. You could check the Alpine radio settings and see if there is something that needs to be changed in order to allow the CD changer to work. If you disconnected the battery connection to the radio then it might have reset the settings to factory default. Otherwise it sounds to me like the problem is with the Sirius reciever.

My CDA-9847 will no reconize the SIR-ALP1 tunner.

I am in the same situation.  I have had my sir-alp1 for 4 years and it simply stopped being recognized.  I called Alpine and they said they have no connection to this piece, it is made by "directed electronics" and I need to contact them.  A new one is around $120 whereas this one was 79 on sale in 2004.  I still have he installation guide/owner's manual for it and nowhere inside is there a number to call them.

With the CNET you do mthis, CD Changer to the sirius input, srius output to the Clarion input. It's just a "daisy chain". I hope I understood you right, if not, you can yell at me :-).

Same problem on my CX-7. I've had antenna replaced one so far. It takes about 30 minutes in the cold (usually on at night on my commute home) to get signal. I agree, during the summer months, everything works fine.

No sound

You most likly have the Data cable in one the other or both plugged into the wrong side, this just happened to me the other day with some Pioneer stuff and I had plugged the input outputs backwards. Everything came up as far as sources showing but now sound. That should fix you up Good luck

No talk radio

After the serial number of the unit is given to the support tech to enable service, it is your subscription that aloows to get those stations. It could be the unit as they said.

Alpine CDA-9855 won't recognize SIR-ALP1

I also had this problem. I had to go through the menu into the setup and then into tuner settings. There should be an option called tuner area. If you set it to area 1 it should start working. For some reason the sirius only works on area one. Hope that solces your problem
