News Illustrated guide to install aftermarket head unit and front speakers in an '08 WRX

Without further ado, here is my "Definative (sorta) and Illustrated Guide to Installing an Aftermarket Stereo and Front Speakers in a 2008 Imprezza WRX" (DIGIASFSIW). I know, I know, the title needs some work, but who gives a flying about the title. On with it already....

Also, using the poll above, please rate the guide. I'd like to know what everyone thinks.

Your pin numbering scheme for the Impreza's 20-pin radio connector is a mirror image of the pin numbering scheme which Subaru uses in its factory service manual wiring diagrams. You refer to the SWC's solid brown wire as connected to pin 6 whereas Subaru's wiring diagram shows it connected to pin 4. You refer to the SWC's solid yellow wire as connnected to pin 15 whereas Subaru's wiring diagram shows it connected to pin 14. Your write-up needs to be changed to either use Subaru's pin numbering scheme or to at least cross reference to Subaru's pin numbering scheme.

Default Time for Rev 1 already

Looks like it's a matter of perspective. The Nissan docs have a different reference point for pin one and they are what I used for reference (because that's the direction Crutchefield pointed me). I will update the guide!

FYI: THE INFO IN THIS PDF IS NOT ACCURATE, JUST MY STARTING POINT. Not to be confused with my guide. The SWC in particular is WAY OFF (I didn't need any resistors at all). Don't be thrown off by the PDF format, I compiled it, I didn't find this somewhere as-is.

Did you happen to check how much room you have to work with for the speakers? (i.e. magnet depth and grill clearance)...

I know the 02-07's have a helluva time getting anything bigger than 2 1/4" deep to fit, sometimes requiring 3/4" to 1" spacers with a lot of hacking just to eliminate interference with the window travel... I'm wondering what kind of room we have with the 08's because my speakers (Pioneer TS-C720PRS) are 2 5/8" deep, roughly 1/4" deeper than your Alpine TypeX.

I'll be doing an install in an 08 STi in Jan/Feb, shortly after the damn thing arrives at the dealer. I will try to take as many pics as possible and do another write up similar to yours. I'll be installing all Pioneer reference equipment as listed below...

DEH-P880PRS head unit (will eventually set it up for an active woofer/tweeter crossover).
TS-C720PRS front speakers
JL 10W3 D4 subs in a smallish 2cu ft box in the back
PRS-D4100F 4ch amp for the fronts (active woofer/tweeter setup)
PRS-D2100T 2ch amp for the subs bridged to 2ohms/channel
Subs will go under driver and passenger seats.

No rear speakers, front stage only for optimal sound quality with active crossover from the head unit.
I'll install some sound deadening, but not too much. I'm not going to coat the doors but I will add enough to make a notable difference, namely a layer on the larger panels and an additional layer of foam against the outer door skin behind the speaker to absorb reflected sound. I'll probably use Second Skin.

Incorrect. 02-04 have issues...05+ have much more clearance. Still not as much as an FJ, but not nearly as restrictive as the 02-04 model years.

You should use spacers anyways for any install. Gives the driver a solid mounting point, helps eliminate resonance, and makes removal a bit easier as well.

Thanks for the correction, but its a guess at best for my situation...
Why do I read so many threads of people having fitment issues with anything deeper than 2" on older models? Do you know if 1/2" spacers are too thick for the 08's?

Point being, the 08's are different and if the factory spacers work fine, why pay for spacers at all? The stock spacers appear pretty solid, deeper than previous years, and they also angle the speaker upward while offering some water shielding. They look like they'd work fine, but if I do need spacers, I'll cut them myself from HDPE or MDF at the correct thickness.

Default RE: Illumination Wire

I didn't actually. My deck has a light sensor on the front and adjusts automatically (I love that feature) so I didn't have a need.

It's the medium purple color wire with little silver spots. There are two purple/pink wires at the end of the harness by the black/blue ground wire. The darker of the two is teh illum wire.

Perfect... That, plus the steering wheel controls are the last things I need to wire. Which color wire is for the SWC?

Nice writeup, Sabba. One suggestion would be to post smaller versions of the pics (perhaps 1/4 size or even smaller), with links to the current size and 5.1MP versions. Currently, the pictures on the main page are very slow to load. Most people will probably need to look at only a few of them in larger sizes.

Another tip: To show depth in the pics of the dash opening, you can stick in a 12" ruler. Adding some fill lighting can help too.
The Impreza's smaller white connector (8 pins) is for the aux input (connector "i86" on Subaru's wiring diagram that Jon posted).

Nissan's pin numbering on the 20-pin speaker/power connector is not simply a mirror image from Subaru's pin numbering...

Nissan numbers the two rows of 9 from right to left, then the outer (larger) pins:
Code:
Nissan
    9  8  7  6  5  4  3  2  1
20                            19
   18 17 16 15 14 13 12 11 10
Subaru numbers the rows from left to right, grouping the larger pins with the lower row:
Code:
Subaru
    1  2  3  4  5  6  7  8  9
10                            20
   11 12 13 14 15 16 17 18 19
(both of these are looking towards the contact pins of the car's connector, with the wires pointing away from you)

Sabba, did you have to program the SWC module or did it just work after connecting the wires?

you have to program the module. which is very simple.

just follow the instructions that came with the module.
or go to: http://www.pac-audio.com


It is mode 3. Once that is programmed in, you have to go through how you want to program the buttons.

Great Guide, sabba...

Does any one out there have a similar guide for a Forester '06, with Manual AC/Heating Controls?

Yes, I did search other sites, and could not find a helpful guide...
