    Do you know which wire is the one for the mute? Thanks

  • Reply Sophie January 20, 2010 at 1:08 pm

    I dont know what to connect the remote amp wire to. The radio constant or radio switched?

  • Reply ModifiedLife January 29, 2010 at 2:06 am

    Sophie, technically you could connect your 2005 Nissan Altima amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 2005 Nissan Altima is on and off whenever your 2005 Nissan Altima 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 with your amplifier install.

    Which color wire is it for the memory of the radio. Everytime I turn off my car my radio resets itself. Can someone please help me?

  • Reply ModifiedLife April 26, 2010 at 2:14 pm

    Carlos, the memory wire is the constant power wire (yellow/green). The constant power wire always sends power to the radio to save your radio stations and other audio settings. Hope this helps. Good luck with your 2005 Nissan Altima stereo installation.

    Is there a way to add an aux input onto a 2005 Altima SL (Bose radio) for MP3 player and/or external SAT radio?

  • Reply ModifiedLife July 13, 2010 at 4:03 pm

    Matt, most late model vehicles do not have inputs to feed an mp3 audio signal to your factory stereo. You would have to install automotive auxiliary input adapter. 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 to add an audio input into your factory stereo. Here is the adapter you will need:

    Auxiliary Input Adapter for 2005 Nissan Altima

    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 2005 Nissan Altima aux input adapter installation.

    I just installed a stereo in my 95 Nissan Altima. But I’m having problems when I turn off the car stereo stays on, even after I take the keys out. Anyone know how to fix this problem??

  • Reply ModifiedLife July 15, 2010 at 12:39 am

    Manuel, you may have mixed up the battery constant and accessory switched wires. The battery constant always sends power to the radio to save your radio stations and other audio settings. The accessory switched wire sends power to your radio only when the key is in the ignition and your 2005 Nissan Altima is on. Check your wiring and make sure the correct radio wires are hooked up to the correct wires on your factory harness. Hope this helps. Good luck with your 2005 Nissan Altima radio installation.

    i just installed an in dash dvd player in my 2002 nissan altima with the bose system which i took out it works fine but the sound out put from the speakers is kinda low compared to when my factory bose is hocked up. and when ever i turn on the ignition then i hear the constant beebing sound from the speakers like it just goes beeeeeeeeeeeeeeeeeeb none stop put when the ignition is off it thoes not do that can any one help me out

  • Reply ModifiedLife August 5, 2010 at 3:10 pm

    Lil T, the reason your in dash DVD player is playing so low could be because the factory Infinity audio system is running on a different impedance (ohm rating). After market stereo head units output audio at 4 ohms while Infinity audio system output audio at 2 ohms. The difference in impedance (ohm rating) can cause your volume to output a higher or lower levels. You may have to remove your Infinity audio 2 ohm speakers and replace them with 4 ohm speakers to match your aftermarket radio. Hope this helps. Good luck with your 2002 Nissan Altima stereo installation.

    i installed an aftermarket stereo including the adapter on my 2005 altima. for some reason when i switch it to cd or ipod mode there is no sound, but when i have the radio playing its fine. i tried switching out deck and the same problem occurred. do you know whatcould possibly be wrong

  • Reply ModifiedLife August 30, 2010 at 11:41 pm

    Sega, your 2005 Nissan Altima may have a factory amplifier that needs to be turned on by your after market radio. The car stereo amplifier trigger wire has to be wired up to turn on your factory amplifier so that your CD or iPod audio output can be heard. Unfortunately, we do not have this information but maybe someone from the Modified Life community can post that information here. Hope this helps. Good luck with your 2005 Nissan Altima amplifier wiring.

  • Reply ModifiedLife November 30, 2010 at 5:34 pm

    Chris, the easiest way to install an aftermarket stereo into your 2005 Nissan Altima would be to purchase a 2005 Nissan Altima Dash Kit and a 2005 Nissan Altima Wiring Harness.

    As for your steering wheel controls, you will need a steering wheel control adapter to keep your factory steering wheel controls:

    Steering Wheel Control Adapter for Alpine Radio
    Steering Wheel Control Adapter for Blaupunkt Radio
    Steering Wheel Control Adapter for Clarion Radio
    Steering Wheel Control Adapter for Eclipse Radio
    Steering Wheel Control Adapter for JVC Radio
    Steering Wheel Control Adapter for Kenwood Radio
    Steering Wheel Control Adapter for Pioneer Radio
    Steering Wheel Control Adapter for Sony Radio
    Steering Wheel Control Adapter for Valor Radio

    Brian, if your 2005 Nissan Altima has a Bose radio, use the pink wire in your 2005 Nissan Altima factory radio wire harness. If your 2005 Nissan Altima does NOT have a 5-speed automatic transmission, use the blue/yellow wire behind the instrument cluster. Hope this helps.

  • Reply ModifiedLife August 10, 2011 at 11:57 pm

    Shane, double check ALL your fuses using a Automotive Fuse Tester because certain vehicles may have a wire tied into another circuit not labeled as car radio. You may have additional fuse boxes by the driver side of the dash, passenger side of the dash, driver kick panel, passenger kick panel, under the steering column or under the hood. If all of your fuses are good, your 2005 Nissan Altima factory amplifier (if equipped) may be faulty. We suggest you take your car to an experienced audio installer and have them troubleshoot your problem. Hope this helps. Good luck with your 2005 Nissan Altima radio troubleshooting.

    Moe, here are the components you need to install an aftermarket single DIN stereo in your 2005 Nissan Altima:

    Single DIN Dash Kit for 2005 Nissan Altima
    Radio Wire Harness for 2005 Nissan Altima

    You will need some aftermarket electronics to hook up a subwoofer to your 2005 Nissan Altima factory stereo. You will need five components:

    1. Car Subwoofer
    2. Car Subwoofer Box to house your car subwoofer.
    3. Car Audio Amplifier that matches your subwoofer power needs and ohm rating.
    4. Car Amplifier Wiring Kit that can handle the power needs of your amplifier.
    5. RCA Line Out Converter to feed an audio signal from your factory radio to your aftermarket amplifier.

    First run all your amplifier power from your car battery to where you plan on mounting your amplifier. Next, run your ground wire from your grounding point to your amplifier. Wire up the RCA Line Out Converter to the rear speaker wires to get a full range audio source. Next, connect one end of your RCA jacks to the Line Out Converter and the other end of the RCA jacks to your amplifier. This will provide an audio signal to your after market amp. Lastly, connect your subwoofer to your after market amplifier using the speaker wire in the amplifier wiring kit. 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 2005 Nissan Altima stereo installation.
