Complicated audio issue

[Maxima_boi]

Ok, first of all sorry if this has been answered! I have a 2001 Nissan maxima with Bose. My friend thought he knew how to install an aftermarket radio without a wiring harness.The car had two white adapters that plugged into the back of the stock radio. My friend clipped one off and he wires went everywhere. The other one was clipped but I made sure I kept the wires into the white adapter just in case I needed to wire it back! I can wire one of them back on but I have no idea what to do with the rest of the wires? I bought a wiring harness so that problem is solved I just need help restoring my car back to what it was so I can install the radio. Any information or ideas would b appreciated!!!

See page 171-187 HERE. Should help you figure things out.

Here is the pin-outs for those plugs:

Ok thank you so much finally got a straight up answer. My only question is, what wire is the ground wire? I got the factory harness and the adapter harness. So I have everything I need to fix my problem. The car has some gray wires are these the grounds?

[zerepdivad]

Nissans generally will ground through the factory metal mounlting brackets.

Ok I wired up the car like you posted. I made sure the stereo had a secure ground. Now when I turn on the car and the radio, I can push the eject button and can hear it eject a cd but now it ejected the cd but I can't put one bak in and there is no lights on the screen or anything. When I wired it up I noticed that there is a gray wire that I dnt have hooked up. The only 2 wires I had left was the ground and the amp ground. I hooked up the ground to the chassis and the amp ground to the chassis! I have no idea what the grey wires are for because they aren't listed above. I also notices that there are 2green/white wires. Maybe I have them backwards?

What do you have hooked up to the red and yellow of the aftermarket radio?

[Maxima_boi]

What do you have hooked up to the red and yellow of the aftermarket radio?

I have it hooked up just like posted above. I believe it says red/yellow is dimmer. I still don't know what the two gray wires are for???

[the converted]

He meant the red wire and the yellow wire on the back of the deck. The gray wires I think ,are just signal shield wires that you don't really need to do anything with. Double check the fuses or the stereo because one of them might have blown. Also, did you, bypass the Bose amps?

OK, let's step back. You/someone cut both plugs off the factory Bose and are installing an aftermarket radio.

From the new radio you have:red wire: Switched positiveyellow wire: Constant powerorange/white (if avail): lighting switchblack wire: chassis groundblue wire or blue/white: amp onwhite: LF +white/black: LF -gray: RF +gray/black: RF -green: LR +green/black: LR -violet: RR +violet/black: RR -

You want to connect the above wires to the cut wires as such:

Radio to factory:Red wire to purple wireyellow wire to yellow wireorange/white wire to red/yellow wireBlack to ground blue or blue/white wire to green/white wirewhite to whitewhite/black to blackgray to greengray/black to redgreen to browngreen/black to black/redviolet to blueviolet/black to black/white The above should get you going. Now, in addition to the above, the Maxima has a switched power requirement for the antenna signal booster (at least it did on my 2002). To use the antenna you had to purchase a converter plug from the round 2-prong factory antenna to the long single plug style for the aftermarket radio. This works fine....except....you will notice your AM/FM reception SUX. If you look at the factory antenna line you should see a single cable coming out of it, I believe it's green (from memory). You will need to supply this with a switched constant voltage in order to get the antenna booster to function. In my Maxima I cut this wire and spliced it in with the red wire from the radio so it will receive power when you turn on the car or turn the key to ACC.

You can actually connect an aftermarket radio's speaker level outputs to the Bose amp and it should work. At least I know of others who have done it and it works due to the voltage required via the Bose amps from a signal perspective. Personally, I didn't go that route as I simply replaced everything.

Ok ill explain this again. I cut off the factory plugs that go into the back of the bose stereo. (2 white plugs) I finally found a place that had the factory plugs and installed them as i was told from here! Once i plugged in the new factory plugs and turned on the car, the factory radio ejected a cd but no digital lighting or other functions work. The only thing that works is the eject button? Then i got the adapter harness (the one used to install an aftermarket radio that plugs into the stock harness)! I wired it up to my aftermarket cd player and nothing. I believe that i could have possibly fried my aftermarket radio when i tried hard wiring it in after i cut the plugs off, but that still doesn't explain why my stock radio doesn't work??? Should i check my wiring again? I checked the fuse. The stock fuse is 15 amp but was burnt up i replaced it with a 30 amp fuse. Is this ok? The 30 amp fuse is still good! Unless there is 2 fuses that controls the radio because there is one fuse that is labeled "audio" that's the one i replaced!

Thank you guys SOO much for being patient and trying to help me out. I know its annoying!

Everything you need has been detailed in this thread. If you are wanting to rewire the factory plugs to the factory system, then reconnect the wiring to the adapters based on: http://www.moodym.com/maxima/a....html

The above links show the plugs, pin positions and which color wire goes to which pin. The last diagram on that page tells you what the wiring colors are for the pinouts.

If you want to use the aftermarket system, then connect it as I listed in the above post.

So, yes, I would suggest you validate the wiring. You can test the aftermarket radio by simply connecting it to the fuse box or even the car battery to see if it will turn on. Connect the red and yellow wires to a single wire and connect that to a 12v positive source and ground the black wire. If it comes on then the radio is probably not fried.

Ok i'll try this. Thanks

Ok I called the local sound system shop and told them what was going on. I told him how the eject button works but no digital lighting or other lights come on. He told me that it sounds like your accesory wire isn't hooked up? So I pulled the car apart again and the accesory was hooked up to the purple wire. Which is the correct wire but still same result!

[zerepdivad]

Honestly you;'ve probably got a fuse blown somewhere. Buy yourself a multimeter and start testing where you aren't getting voltage.

[audtatious]

If you look at the pinout, the purple wire is the switched positive. Reread my wiring diagram.

[Maxima_boi]

Well what fuses would caus the radio not work besides the fuse labeled "audio"

[the converted]

I take it you haven't looked at the one under the hood then.

[Maxima_boi]

Ok I have no idea what that means? Does that mean I have I hooked to the wrong one?

[Maxima_boi]

I

I take it you haven't looked at the one under the hood then.

yeah that's the one labeled "audio" that I changed!

[the converted]

There is also one in the car in the kick panel that might have blown.

k I'll check my fuses when I get time

[Maxima_boi]

Ok i finally got time to mess with my radio again. I changed the display wire or the red wire. i got display and power to my bose system working but none of my speakers were working. Then i hooked up my aftermarket radio had it working and everything, i turned it up and i heard static and then all of the sudden it shut off. I figured i blew the aftermarket radio but i hooked it up to the battery and it turned on! Now everything i do seems like the display wire isn't hooked up, is there anyway possible that the display wire somehow blew or fried?? i checked my fuses, the stereos have power just no display after they just had display and were hooked up correctly????

[audtatious]

Everything you need to know concerning correctly wiring the system is in the above posts. As you are still having difficulties my only suggestion is for you to take it to an audio place and have them determine the issue.
