  1. I’ve purchased a 99 Honda accord and the back speakers are not working. I’ve replaced the stereo with a factory Honda stereo. They are still not working. No power to the back speakers. Is there a stereo amp? If so, where is it located?

  2. Ryan, yes you will have to remove the door panels in your 1999 Honda Accord. Most door panel removals can be done with a Phillips screwdriver and door trim removal tools. Just look for screws at the edge of the door panel, near the door handle or inside the door pull. Once you remove all the screws or plastic tabs, you should be able to use the door trim removal tools to pull the door panel off with ease. Hope this helps. Good luck with your 1999 Honda Accord door panel removal and speaker installation.

  3. you seem to be on point with the 99 accord radio color code but based on your codes and process of elimination i am left with 3 wires , a red one, a blue one and a black one. im bringing this up because i would like to know if my harness is missing a wire or if it has 1 too many please tell me what u think. anyone? thanks.

    hello i like to take a moment to say that your guys are awsome and i will writte if i need your guys thank you very much!

  5. Evan, that auxiliary input adapter does run on FM frequency but not through the air. It provides an audio signal directly to the back radio through the antenna plug so there is no interference. This interface is specific to your 1999 Honda Accord.

  6. Evan, an automotive auxiliary input adapter will allow you to input any mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo. Here is the adapter you will need:

    If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 1999 Honda Accord aux input adapter installation.

  7. Hi There! I’ve got a 99 Accord with a CD player AND a cassette player (the cassette player is in the compartment underneath the stereo, above a storage compartment and 12V electrical plug-in. I was wondering if it would be possible for me to take out the cassette player and install an auxiliary audio cable for my iPod in its’ place. I’m not too great with cars, but I’m pretty good with technology and following directions. Also, my CD player keeps giving me error messages – would it be smart just to get a new stereo even though this one has the built-in security system? Thanks, Evan.

  8. I installed an aftermarket head unit in my 99 Accord coupe several weeks ago and had both an illumination wire and dimmer wire coming from the factory harness. I decided (dumb mistake) to connect both wires to my head unit’s illumination wire without checking switched voltage. Now none of the lights on my dash work (instrument panel, a/c control etc). No blown fuses and both of the illum wires show 12v with the lights on. Any ideas? I am stumped.

  9. Tim, if your radio works just fine in a different vehicle then your factory or after market amplifier may be faulty. We suggest you replace the factory or aftermarket amplifier. Hope this helps. Good luck with your 1999 Honda Accord amp troubleshooting.

  10. have alpine in 99 accord and the rear speakers stopped working. I swapped with a kenwood out of my truck and same thing, no rear speakers. Alpine works fine in truck. What could it be. I have a hard time believing both speakers stopped at the same time. System has been in the car for over 5 years with no problem.

  11. My car battery keeps dying every morning. My friend and I have been testing this for the past week and can’t seem to find an answer. Battery was tested at autozone to to be good, and the amps don’t seem to be the problem either. I was wondering what was causing my battery to die out every morning. Amps turn off when car turns off, everything works fine. The only problem that I may suspect is the wiring on the stereo. I found the amplifier remote wire on my headunit and just used that. Do you know what the red wire is for? That’s the only wire not used by my headunit and the diagram above doesn’t seem to have what the red color wire is.

  12. Quan Lin, technically you could connect your amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever the car is on and off whenever your car is off. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good Luck.

  13. Hadrian,

    We are not aware of any factory subwoofer that comes with the 1999 Honda Accord. As far as we know the rear deck only houses two factory speakers. Hope this helps.. good luck.
