Alpine CDA-7892 CD Player - Answered Questions & Fixed issues

You didn't specify if you wanted the display brighter in the daytime while headlights are off or if it is too dim when the headlights are on, with respect to the rest of the instrument panel illumination. Too bright is easier to deal with but too dim is tough. If it is always too dim under but daytime and night time conditions the only way to improve brightness would be to very gently disassemble the front panel (easier if it is the removable type) and determine what provides the back lighting. If there are tiny LEDS you could painstakingly add more LEDS or swap them out for brighter LEDS. There could be a lot of guesswork determining if this or that LED was brighter than what is in the unit as built. It may just be easier to live with it as-is.

The install diagram indicates the Audio Interrupt wire goes to a Vehicle Phone. If you don't have one, don;t connect it to anything andmake sure you put tape over the end so it doesn't touch ground or a power source.In cases where I don't have or cannot get a wiring harness adapter to plug directly into my vehicle wiring harness I have a trick I like to use. I don't like to cut and remove a vehicle harness socket, I may want to keep the aftermarket stereo when I sell or trade and put the original stereo back in place. Instead of removing the socket I skin back (but do not cut) the wires I need to tap into and wrap the aftermarket unit's wires around the now exposed socket wiring, then solder each one & wrap each one individually with electrical tape. This gives you a secure connection and when and if you need to permanently remove the aftermarket unit you just untape the wires, clip the fatermarket wires off one at a time very close to where they are tapped in, tape each one of them again and there you have the factory plug ready to plug back into the factory stereo.

This could easily be a means to mute the stereo when you are on the phone or say at a teller window at the bank. It could operate by grounding that wire or making it high (+12 vdc). I;m not sure which is appropriate but it is safer to just ground it first to see if that kills the audio rather than sending + 12 VDC into something that turned out to require a ground instead. I don't think you actually have to use it if you have no need for that feature.

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).

I found the manual at Alpine.com.http://vault.alpine-usa.com/products/documents/OM_CDA-7892.PDF

Does this happen often or was this a one time issue and you still don't have sound?

If its a one time issue there's a fair chance that a fuse blew and will need to be replaced.

I've had this happen to me quite a few times and fuses can be fairly cheap.

do you have a amplifier in the vehicle?

Yes it does have MP3 capability.

In the set up menu (press and hold set up button for at least 3 seconds) you need to select CD/MP3 with the up or down buttons. Then use Band button to make sure CD/MP3 is selected and you can play back MP3s that are burned to CD and also ordinary CD tracks.

Thanks for using FixYa. Please do leave a vote for the solution.

u have to buy a special adapter

You need a dashkit, wireharness and antenna adaptor. It all is vehcial specfic so you need to look in up for the make model and year. Use schoche or metra online to give you the part numbers of the kits some cars will not require the dashkit or the antenna adaptor.

are you running the speakers through an amplifier? if so, it sounds like you are using the blue wire which is the antenna remote to turn the amp on. instead use the blue/white wire.

Good Evening, I am sorry to hear you have a battery draw however the voltage and amperage draw should be very low if the radio is installed properly. I have seen seat switches and lock switches that get stuck create a draw to kill a battery. I am sure you checked to make sure all your interior lights are off at night, so the next logical step is to get a test light and disconnect the positive battery cable. Place the test light between the battery and the cable end and it will light up with a draw. Then go through and pull fuses out one by one until the light goes out. 1 or 2 fuses may do it. I would check the wiring on the radio to be sure first, maybe even unplug it overnight to see if that is your problem for sure without disabling the battery fuse. Hope this helps.
Thanks,
Joey

You have to bypass your entire factory system, it takes some customizing and careful installation, too much information to write over Fix Ya advice, phone or actual physical support in a car stereo shop is your best bet.

Good luck my friend.

You may have your speakers wires shorting out somewhere. Try to isolate each channel till you find the one that is shorted out. It is all a case of trial and error. As long as you do not remove the power wire or the constant wire then you can troubleshoot your speaker without causing any harm. Usually there is factory sticker on the underside that says what speakers are which and what channel they are (left front, left rear and so on. Let me know if this helps if not there are more things you can try

hook up the ground and twist the red and yellow together and hook that up to a wire off the battery then try and see if the head unit comes on quick way to check and see if the deck will come on works for me. hope this helps,
