    I have a 2002 Dodge Ram 1500 and I wish to replace my stock stereo for an in-dash.. The only problem is I have the steering wheel controls for my stock system and I don’t know how or if its even possible to still use those controls with a non-stock cd player.. Let me know.

  • Reply ModifiedLife May 29, 2008 at 12:15 pm

    Tyler, as far as we know it would require extensive re-wiring to get the stock steering wheel controls to work with an aftermarket radio. If you’re not an expert car audio installer, your best bet is to get an after market radio that comes with steering wheel controls of its own. Hope this helps. Good luck.

  • Reply Paul July 1, 2008 at 1:02 am

    Look out Tyler. You may have a 2002 RAM 1500, but your stereo is wired as a 2003 one. My P/U was manufactured in 2/02, but already had the 2003 wire colors. Good job, folks, for having this info!

    To witch wire do you connect the blue remote wire from a after market amp on a 2002 Dodge ram 1500. To the red constant battery, red&white accessory switch, or to the yellow antenna trigger wire would really appreciate the help asap? Thanks guys

  • Reply ModifiedLife July 23, 2009 at 6:18 pm

    Jorge, technically you could connect your 2002 Dodge Ram 1500 amplifier turn on wire to the accessory switched 12v+ wire. That way your amplifier is on whenever your 2002 Dodge Ram 1500 is on and off whenever your 2002 Dodge Ram 1500 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.

    Will my amp be turned on if my key switch is turned all the way back on my 2002 dodge ram 1500, and why do i need the 1 amp fuse on the turn on wire to the ampplifier?

  • Reply ModifiedLife July 29, 2009 at 2:49 am

    Jorge, it should be turned on when the key is turned all the way back because you will be using the accessory switched wire which is the wire that powers accessories like the radio, etc. The 1 amp fuse on the turn wire is used to protect your factory wiring. Hope this helps. Good luck with your amplifier installation.

    My son went thru a wash (full of water) and now the stereo (origianl equipment) will not work. I also notice the seat belt signal stays on even when the seat belt is engaged. The fuses are ok. What could the problem be?

  • Reply ModifiedLife October 26, 2009 at 6:22 pm

    Ray, it would be tough say what is wrong but it sounds like you may have a short in your stereo wiring. Our advice is to have an experienced installer look at your radio wiring and fix the short. Hope this helps. Good luck troubleshooting your radio problem.

    When balance and fader buttons are placed in the middle, is it normal that the rear speakers sounds lower then the front ones on my Infinity sound system on my Dodge Ram 1500 SLT 2002?

    2002 Dodge Ram 1500 Quad Cab. My AM/FM Cassette stereo radio turns on and has volume, left & Right balance and front & rear balance. The problem is none of the other buttons function. Seek, channel selector, preset buttons, clock settings. So I can’t change the channel, select AM or FM either. Is there another fuse for this or is my stock stereo just dead or broken?

  • Reply ModifiedLife July 20, 2010 at 2:25 pm

    John, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, your factory amplifier or your car stereo audio output 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 2002 Dodge Ram 1500 Quad Cab radio troubleshooting.

    I have an 03 dodge ram 1500 and every time I turn off the truck and restart it I have to turn the dtock radio on and redo the am/fm settings and the bass/trem/fad/bal settings also there are no radio lights on it at night??? Is there more than one fuse for the radio?? or what might it be?? thanks.

  • Reply ModifiedLife August 16, 2010 at 9:55 pm

    Tim, 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 2003 Dodge Ram 1500 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 2003 Dodge Ram 1500 radio installation.

    Do you need an aftermarket head unit to put in a sub or can you hook it up to the stock stereo?

  • Reply ModifiedLife September 1, 2010 at 5:43 pm

    John, you do not need an aftermarket head unit to put a subwoofer in your 2002 Dodge Ram 1500. You would have to install a line out converter to supply an audio output to the after market amplifier powering your subwoofer. Here is the Line-Out Converter you need:

    Scosche 2-Channel Speaker to RCA Line Out Converter

    When splicing in the RCA Line Out Converter, tap your factory rear speaker wires to get a full range audio source. We suggest you invest in some solid wire taps that wont come loose. These wire tap connectors will allow you to tap into wires without cutting and installs in seconds by hand with no crimping or tools required. 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 2002 Dodge Ram 1500 amplifier installation.

If all of your fuses are good, your 2002 Dodge Ram 1500 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 to output sound from your speakers. Hope this points you in the right direction.

    I have a dodge 2500 extended cab and im trying to change out the factory stereo with an in dash cd player. My problem is that there is a single black /blue wire that connects to the back of the stock stereo and when i hooked up the new cd player it wouldn’t turn on. I hooked the stock stereo back up and unless the black/blue wire is hooked up it wont turn on. I was told it was for the factory amp so I bought a bypass harness for it and couldn’t find an amp. everyone I’ve talked to says it behind the glove box but there isn’t anything there or anywhere else that I’ve looked. Im pretty sure that it has an amp but I just can’t figure out anything anywhere to fix this problem.. any ideas??

    hello i just bought my 2002 dodge ram 1500 it has the infinity stereo in it the owner said it worked great for him and then just cut off one day. the display on the stereo lights up and everything but there is no sound all it does is ticks from the speakers i checked all the fuses and every one is good, i changed the factory stereo with my alpine deck and still all it does is ticks, i hooked up the remote amp wire like you said in previous tags and still get the ticks. is there anything else i can check or is there a way to bypass the oem amp to get some sound. i think there used to be a Sirius radio in it at one point because there is a antenna on the roof for one, could that be what messed it up when it was removed. thanks

  • Reply ModifiedLife October 20, 2011 at 11:06 pm

    Mike, double check ALL your fuses using an 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 2002 Dodge Ram 1500 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 2002 Dodge Ram 1500 radio troubleshooting.

    Having read numerous complaints about the OEM radio on the 2002 Dodge Ram 1500 Quad Cab working for 5 seconds and then the sound goes away, it’s obvious to me it’s common problem. Having checked the fuses and radio connections, all appearing ok, can I assume it’s a bad component on a circuit card or is there another explanation? No one has responded back to any of these issues before, now is the time for the REAL Super Tech to save the day! We need your help….

I’m also experiencing the no sound problem and if that is the plug for it , what wire in the aftermarket radio can I splice those wires into? can anyone help?
