After successfully installing my single DIN stereo
I decided to put in my speakers in the rear since the weather was so nice out.
Again, this is just a quick DIY to help you guys out. Also, there are currently no aftermarket installation kits for single DIN stereos or quick connects for installing speakers without cutting the factory wires for the 2012+ Sedans.
What you need:
Black rubber sealant (optional)
Speaker adapter plates
AA or AAA battery (optional)
Here is the door panel with manual crank windows:
First thing we need to do is to remove the window crank. Make sure the window is up and the handle is pointing up. There is no need for a special tool that you will only use once. Instead, use a soft microfiber cloth and slide it between the crank and the black circular piece behind it. It is important to do it just as the picture shows because the clip is in a position where the cloth can remove it.
Good job. You should now have this:
Next, use an allen wrench to remove this little bolt. After you remove this bolt you can pull the pocket out. It is clipped in there so it takes a slight tug to get it out.
It leaves you with this
Not you need to remove this screw which holds the panel to the actual door:
Here, take a small flathead screwdriver to pop out the middle tab which will allow the whole plug to come out.
After you get this plug out all the holds the door panel on is clips and the lip on the top. I always start to pop the door panel off on the left side of the speaker since there is a lip that you can grab and pull. After getting the door panel off you have this.
Remove the screws holding the speaker, remove the plug into the speaker, and pull back the foam to see what color wires you have.
I looked all over and could not which was positive or negative. So, I took a AAA battery and put a wire on each end. I just used the wires that came with the aftermarket speaker. Heres what it looked like.
Then I put the wire on the leads to the factory speaker. NOTE: Doing this can cause possible damage. But, since it is the oem speaker it isn't much concern to me. When the speaker cone moves OUTWARD you have successful wired it up correctly. This tells you which side is positive and which side is negative. In my case, the red wire is positive and the white wire is negative. Phew! Glad we got the figured out! (Though some people hook them up backwards on purpose...won't do any damage)
Now that we've got the polarity figured out you can cut off the factory plug (which i hate doing). Make sure you have plenty of room to strip some wire insulation as well.
Now, solder the wire/connectors that come with your aftermarket speakers to the OEM speaker wires. Generally, the bigger tab is positive and the smaller tab is negative. Also, be sure to solder PROPERLY. An improper solder with be dull and can increase resistance and likelyhood of breakage. here you can see I have great shiny solders.
I added electrical tape as well just to make sure everything is insulated.
After looking things over and not having any rubber grommets I decided this was the best place to route the wiring. I punctured a hole in the plastic.
Then I put tape over the hole and pierced it again. This will prevent the plastic from cutting and separating. You dont want that to happen because then the wires will be against metal and can rub through the insulation causing very bad things to happen.
I've got the wire routed through the hole and I also added tape to the wires just as another barrier in case there is any rubbing.
Here is a picture of the speaker adapters you need. Note that the foam came with the aftermarket speakers.
HOWEVER, I bought these for the front speakers off ebay for $13 shipped hoping they would fit (Nissan/Infiniti OEM Bose speaker adapters). THEY DO! There was NO modification needed and they already have foam on the backside. PLUS, they have the same prongs that go into the door as the OEM speakers so there is no way the speaker can move around. The ONLY thing I had to do was install the Right Front speaker adapter on the drivers door and the Left Front speaker adapter on the front right (this made it so the baffle was up so it would wash water away from the speaker instead of acting like a cup and collecting it.
Attach the wires to the speaker terminals.
Attach the speaker to the speaker adapter.
With that done, I used the black rubber sealant:
And here is is on the speaker adapter ring right before I mounted it to the door. I use this to create an airtight seal and also to prevent rattles. These are the adapters I used for the rear speakers. They fit great without any problems.
Here it is all done! Now your ready to listen to decent quality audio instead of the terrible OEM speakers/headunit.
Now all you have to do is put everything back together!
Feel free to ask questions. Hope this helped you guys!
