Step 4 - Mounting the new equipment
Start by removing the 4 screws which hold each bracket onto the side of the deck.
We will now use our newly freed brackets to hold our new stereo and din pocket. If your head unit utilizes a flip down faceplate, you will likely need to mount it in the top slot of the bracket, as the trim panel will interfere with the path of the face when mounted in the bottom. Use the same screws which held the stock unit into place to mount the aftermarket unit. During this time, we will also mount the din pocket. I purchased mine at a local Tweeter for $20. I have heard that there are units available off the Legacy and Forester which will also fit nicely, but my local Subaru dealership was somewhat less than helpful when I inquired about one. I had to slightly modify the pocket to make it fit in the bracket without bending anything, but this should be easy enough for you to figure out. Note that I did not use any screws to hold the pocket in place. There are tabs which will slip through the marked hole in the picture below which should be enough to hold the pocket in place.
Step 5 - Back in the car
After everything is mounted to the brackets, it is time to connect it to the car. Connect the proper harness to the back of the head unit. Next, connect the ground wire to the side of the bracket before plugging the other harnesses together.
I highly recommend testing to ensure everything works before reassembling the dash. There are few things more frustrating than putting everything back together, only to discover you forgot something, or the unit is not working properly. For now, we will only slide our mounted equipment into the dash, but will not screw it in place.
Reconnect the negative battery terminal if you have not already done so. Cross your fingers and turn the key. Hopefully, your unit will start up without any problems. If the unit does not power up after installation, first check the factory fuses to ensure they are not blown. If the fuses appear to be working properly, take the radio out and connect it directly to the battery. The red and yellow wires connect to the positive post and the black ground wire should go to the negative post. Turn the deck on to see if it works. If it does, recheck the yellow and black wires in the dash.
You can take this opportunity to run additional wiring as you see fit. I will be installing an amplifier at a later date, which will be covered in another topic. For now, I will simply install an iPod connection cable.
There is a hole in the back right side of the dash where we can run our cable directly to the glovebox.
Now that all of our connections are made and we have run additional wires, we can safely mount the bracketed contraption in the dash.
Reassembly should be relatively easy and straightforward. One thing to note, however, is that the cupholder needs to be reinserted before attaching the trim panel, as there is a tab underneath which will get hung up on the trim.
We are pretty much finished now. Enjoy your new stereo!
