3.5mm input jack to stock amplifier
"I decided to remove the headunit from my car so I could use the space
for adding gauges. But I still wanted to be able to listen to music.
Since I already had a pre-amp adapter harness I decided to try
connecting a 3.5mm stereo headphone jack on the pre-amp lines. So far
with all the devices I've tried (iPod, cell phone, portable MP3 player)
their built-in volume control was more than capable of varying the
level from quiet to loud/distortion. Since a few have asked about it I
thought I'd add a short how-to thread.
First, I started with the Metra 70-8112 adapter harness. This plugs in
to the stock stereo harness and provides the wiring to connect an
aftermarket headunit using pre-amp outputs. This maintains the OEM
amplifier. The wiring pinouts for this are shown below:
You need to add a way to turn the amplifier on and off. Do this by
creating a switch between the blue/white (amp turn-on) and red (+12V
with key on) wires. I added a small connector to make removal simpler
when I pull the dash panel off. This is shown in the image below:
For a quick test I used adapters (from Radio Shack...I know...chinsy).
You'll need two (2) of the 2 Female RCA in, 1 Male RCA out, and one
stereo Female RCA to Female 3.5mm phono cables. This is wired such that
the front and rear right channels are joined together, and same for the
left channels. This is shown in the image below:
Turn the system on by closing the switch, and use a 3.5mm stereo phono
cable to the headphone output of your favorite device. If I like this
I'm sure I will get rid of all the RCA connectors and solder the wires
from the phono cable directly to the Metra harness. But for now this is
very reversible in case I want to install a headunit in the future. " -Dan
