  1. Robert, not necessarily but a wire harness will make installing a radio easier. Just follow the car stereo wiring diagram above and match up the correct wires with the wires on the back of your aftermarket radio. Hope this helps. Good luck.

  2. hi i have a 2001 cadillac dts. i want to put in a new system but kee pthe stock head unit. i want to wire the stock 8 inch sub to my amp with rca cables. is this possible>?

  3. Alex, you can wire your stock 8 inch subwoofer to an aftermarket amplifier. Just make sure the subwoofer and the amplifier are both the same ohm rating to make things easy. You can either splice in a line out converter or find an amplifier that accepts a speaker signal straight into the amplifier. Here is the Line-Out Converter you need:

  4. Hey i also want to install an amp and sub in my trunck and run the wires up front to the stock head unit. any ideas how to remove the 2001 DTS head unit without causing any damage?

  5. What are the specs on the OEM sub in the 2001 Deville. My sub is blown and I would like to replace it, but I want to utilize the OEM amp…so I want to make sure I match the specs as closely as I can. Thanks!!!

  6. Bill, the speed sense wire is the dark green/white wire on the back of the instrument cluster. Hope this helps. Good luck with your navigation installation.

  7. i just recently bought a 2001 cadillac deville, i can not figure out how to replace the sub woofer in the back dash, its blown. also, any pointers where to find a replacement speaker?

  8. John-Paul, you may be required to remove the deck lid from the interior of the car. On some cars removal of the rear seats is required to get to the rear deck lid. Also, when choosing a replacement subwoofer, make sure you replace the blown speaker with a speaker with the same ohm rating. Hope this helps. Good luck with replacing your speaker.

  9. i have 3 12 inch subs and a amp i want to run to the factory radio and need to know is the blue wire the remote wire so i can run my amp

  10. I have a 95 Deville and wondering if the trunk is prewired by the factory for a CD changer? If anyone know please let me know. Thank You.

  11. Adam, you will need an automotive auxiliary input adapter. This 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:

  12. to remove the stock sub on a 2001 cadillac deville. get a flat head screw driver and pop out the clips on the top of the backseat it should be four of them and the rest you ll figure out. I also purchased after market subs to replace the stock but i was told that the stock was 8 inch but when i took it out it was way larger than the a 8 in. it was a 10 inch sub.

  13. Hi I recently put in a new aftermarket radio, everything was working great, then i decided to put in an audio system in.I pulled the radio back out to hook up the rca’s when i put it back the deck would not turn on so i checked all of the wiring I installed and found the 12v turn on was disconnected. I hooked it back up the radio turned on but the right off. I checked the 12 v turn on wire, NO CURRENT, So i figured it was a fuse checked all the fuses NOTHING………… now i am stuck. any help would be greatly appretiated

  14. Stephan, it would be hard to say what is causing your radio to turn on and then right off. Our advise is to double check your radio harness and make sure the wire connections are solid. It seems like when you pulled your aftermarket radio out you may have loosened some of the wire connections. Hope this helps. Good luck with your 2001 Cadillac Deville stereo troubleshooting.

  15. I purchased a 2001 Cadillac DTS Deville last year. I need the buttons on the front of the stereo replaced. (everything is warn off) Where can I go to have this done?….car is beautiful…this makes it look awful…

  16. Karen, you can source a 2001 Cadillac DTS factory radio either at your local Cadillac dealer or at your local junkyard. Hope this helps. Good luck with your 2001 Cadillac DTS factory stereo search.

  17. hi i recently decided to go with two 10 in after market subs wit a pretty power full amp but i kept the factory head unit, i got everything installed correctly but the problem im having is when i turn the music up and the bass plays for a min or so then just starts playin the music in different note with the bass going up and down fading in an out, i dont know whats wrong. what could cause this??

  18. What are the specs on the OEM subwoofer in the 2001 cadillac Deville? I want to replace the sub without buying a new amp. Anyone know?

  19. I need to know where i can get a radio bracket for my 2002 cadilac seville sts. Customs sounds told i couldnt put a aftermarket radio in it, but i have seen a couple of the same cars with aftermarket radios.

  20. Does anyone know exactly where the stock amp is located? I know it is in the rear behind the seat but where? Can I find it on the right side ,left side, is is accessable from the trunk or the back seat?

  21. I installed 3 12 inch tarantulas in my 2001 cadillac deville (base model) Everything is running great and sounds unreal. The only problem that Im having is the air pressure from the subs is pushing the factory sub in the back hatch up so hard it rattles. Its probably rattling pretty loud but with the system being so loud in general you can hear it just enough to ruin the perfection. Removing the factory sub would be a last ditch option but that sucker is in there pretty good. Anyone know a way to keep the air pressure from pushing up on the factory sub?

  22. Tyler, yes you can hook up your an amplifier and subwoofer to your stock stereo. You will need some aftermarket electronics to hook up a subwoofer to your 2001 Cadillac Deville 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 2001 Cadillac Deville amplifier and subwoofer installation.

  23. I have a 2001 Cadillac Deville Northstar, recently I purchased a Boss radio, along with the Pac Os2-gm32 radio wiring harness, and when I hooked it all up the radio came on but there was no sound. Can any please assist? It is my understanding that this vehicle has a factory amplifier. It also has onstar which I do not use or care to use.

  24. Rodney, 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 make sure all of your fuses are not blown. If all of your fuses are in working condition, your 2001 Cadillac Deville may have a factory amplifier that needs to be turned on by your after market radio. The car radio amplifier trigger wire has to be wired up to turn on your factory amp to output sound from your speakers. Double check that your 2001 Cadillac Deville amplifier turn on wire is connected. Hope this helps. Good luck with your 2001 Cadillac Deville radio installation.
