2012 STI Stereo Build with OEM NAV H/U

[Lateralis]

Ok 1st off I tend to ramble alot and my thoughts might be a bit scatterd so I appologive before hand.

So I just got my 2nd Subaru, a 2012 sti ltd with the nav pkg. I love the stock H/U as it does EVERYTHING. Bluetooth, HD radio, Ipod, Aux-in, XM, everything that I would ever need in one nice little pkg. However, the stock speakers need to go so that I can obtain musical euphoria.

Before I got rid of my old wrx I took out all of my stereo equipment.
2 sets of JL Audio XR-650csi
1 set of JL Audio XR-650cxi
2 JL Audio 12w6v2-d4's
2 Alpine PDX 4.100
2 Alpine PDX 1.600
Eclipse AVN5510

That set up that I was running was overkill, but awesome.

What I'm looking to do with the new car is Run 3 way components in the front, either leave the rears stock or put in the xr-650cxi's, and run 1 of the 12w6v2's.

For the 3 ways up front I'm considering the Focal 165-VR3's. I don't have alot of experience with them, but I hear great things about the Focal component setups.

As for making this work I need a sound processor. I've ruled out using a LOC and more specifically something like the Audiocontrol LC6 or LC8. I'm basing that decision off of the stock H/U DSP. With the upgraded speakers and amplifiers all the crap that was covered up by the inability of the stock speakers to reproduced is going to come out and sound like complete crap. Along with that would be Bass control. Most oem h/u dsp will muddle out bass for the most part as volume goes up. With all this being said I need to cancle out the stock unit dsp and get that flat eq and the only way I'm going to get that is with a aftermarket sound processor.

The one's that I've looked into so far are the JL Audio Clean Sweep, JBL MS-8, and the Alpine PXE-H660. Alpine also has something new that I think is supposed to replace the PXE-H660, but from what I can tell it is not on sale yet.

I have NO experience with sound processors at all and actually have never seen how they are set up. Also since I'm going to run 3-way components up front I think it just made things even trickier.

Ok on with the questions.

1: Now I'm guessing that my '12 is like most others and does not come stock with amps therefore making everything out of the H/U speaker level signals. Where are people taping into these lines? Are they splicing them right at the radio harness or what?

2: What would you recomend for sound processor considering my overall goals?

3: Do sound processors remove the need for the crossover provided with the speaker sets? I noticed that some of them ( JBL MS-8 ) say that they have built in crossover point/slopes.

4: If the above is "yes" would I be better off mix matching components than just buying a complete set and what would your speaker recomendations be?

5: Do sound processors remove the ability to control volume from the H/U? I can deal with having to open the glove box to deal wit the EQ but having a remote volume knob seperate from the H/U is NOT an option I'm willing to consider.

Lastly I'm not really on a budget but not looking for stuff that is stupid expensive. I will post my build in here once I start it.

Thanks for your opinions guys!

keeping the OE HU is not an issue...

Alpine currently offers nothing... the H660 does the integration part... but offers limited processsing..

The Jbl MS8 or the audison bit-one are the only "integration" processors readily available... well the mini-dsp is an option.....

right now... getting 3-way front, rear fill AND 5.1 or more processing.... yeah... I dream of the PXA-H900 etc every day when I try to re-evaluate my system....

In my opinion, if the newest Alpine PXA-H800 actually materializes.. awesome...

there needs to be a TRUE 3-way front, 2-way rear fill, + sub , + Center channel... 5.1+ ALL channels active.. So basically a TEN(10) channel rca processor.

Mini DSP is the only current option... u-build it...

People have reported huge gains in sound quality when using this http://www.crutchfield.com/p_161LC6I...er-reviews-tab and aftermarket amp for the speakers.

I know its not an EQ flattening processor, but its the route I am going to go...its cheaper and seems to have very positive reviews.

[Lateralis]

Ok, well been doing a lot of research on other forums and have decided on the direction of my project.

Here goes:

JBL MS-8 sound processor
Alpine PDX 4.100
Alpine PDX F6
Alpine PDX M6
HAT Legatia L641-3 Pro Component Speaker Set
JL XR-650cxi "rear fill"
1 JL 12 w6v2 d4

Still have a bit of a shopping list since I'm not reusing a lot of my old equipment. Being this will be my 1st actual SQ style build I can't wait to start putting this all together!

Now on to the 1st hurdle. The radio harness... oh yes... I'm going to be getting a break out harness from ae64. Anyways here are some pics that I took while I was in it.

Side note: Fujitsu Ten is the same company that makes Eclipse. This is probably why I really like the H/U other than the fact the DSP sucks.

That's the Toyota influence within Subaru. Subaru always used to use either Clarion (which is a Nissan keiretsu company), Kenwood or Panasonic. Toyota's main stereo manufacturer is Fujitsu Ten. As far as stock headunits go, Fujitsus have always been the best I've had.

Really? All I know is the 2011 Forester and 2012 WRX headunit is the absolute worst factory CD player I have ever experienced. My 06 Accord plays CD's that look like my dog ate with ease, while a fleck of dust causes my SUbaru players to skip like crazy.

Is it the Nav or the base unit? I'm not sure what the base unit is since I haven't seen it.

I've had Fujitsu Ten headunits in two Toyotas. My Legacy came with the craptastic Panasonic wedge with useless dual climate control that cost me $350 to replace before stereo since I had to order the JDM Double-Din

Subaru headunit nomenclature

If your stock headunit model number starts with the following, then it's made by:

P - Panasonic
PE - Pioneer
CX - Clarion
GX - Kenwood
FT - Fujitsu Ten (Eclipse)

The 2012 Impreza navigation headunit is the first I've ever seen for Subaru made by Fujitsu Ten. The 2012 Legacy premium non-nav color LCD screen is made by Pioneer. This has to be the Toyota influence as almost all of their headunits are made by Fujitsu or Pioneer.

Hello
it seems that it is not true for the toyota gt86
6 pin connector 1 2
6 5 4 3
10 pin connector 1 2 3 4
10 9 8 7 6 5
connectors 16 and 28 pins it's good

I really appreciate the post I have two pictures don't work when you have time no rush can you repost the pictures in the middle of trying to figure out my Harman/Kardon HU. To upgrade it.

[speakerpimp]

Sounds like an awesome setup!!! Where are you thinking for the 3-way locations??

Well For the Tweeters I'm pretty sure I'm going to have to stick them in the bottom of the a-pillars like you did, but I don't plan on hiding them. Will most likely be similar to the other thread with the 2012 sti.

Now with the Mid-bass and Mid-range I haven't really decided yet. My 1st idea is putting the mid-bass in the stock speaker location. Than putting the mid-range below the leather arm rest thingy on the door. Pic for reference lol.



I'm thinking this mostly because 1) doing a kick panel to me is out of the question. 2) I think the ms-8 will be able to properly set the stage even though the MR and MB are not located next to each other with its time delay. Doing this would keep the install fairly simply as I would only really need to make a grill for the MR's. I still need to do some more research though to see if this would be a problem having the MR so far back.

My other idea is to mold in a pod just forward of the armrest. The L4 isn't a very big speaker, but really the deciding factor is going to be when I actually get the speakers in my hands so I can physically see what I have to work with. I also don't want to make it seem like what I am putting in there is a foreign object either if you know what I mean. More to come as things come in.

Thoughts and opinions welcome!

[speakerpimp]

Super cool! Always nice to see someone with the balls to take on a three way install!!!Well I am all about letting people do their own thing and trying not to "jade" them with my opinion, but I will say that the difference in path-lenght is most important at 400hz so whatever plays music in your system within an octive of 400hz should have careful consideration on how far away you can get them from you. The farther the better. Your ears hear differently at different frequencies so like tweeters for example, your ears hear more through intesity rather than timing cues so it is easier to manipulate with aiming and processing.with the mids maybe in the dash pointing up or kicks that kept the factory shape would be a couple of places I would start looking at. Don't trust the processor to be able to fix everything with delay. Delay is sweet for sure but it comes at a price in response, and the more you help the ms8 with location the more it will be able to do for you in return. IMO of course. Good luck!!

Thanks for posting the pics!

I also just received the Subaru wiring diagrams from another 2012 owner. The HU has a diagnostics screen that mentions the rear camera input.

2012-2013 WRX/STI nav (mfg by Fujitsu Ten) [FT navs in Impreza, Crosstrek, Forester, and BRZ all have different model numbers]

Front: FW602US
Fujitsu Ten Type: FT0021A
Subaru: 86271FG600
Rear: WN60

FCC ID: BABFT0021A
IC: 2024B-FT0021A

The 10-pin and 6-pin harnesses are for power and speakers. Subaru is also using those for 2012-2014 Legacy/Outback models with the 'premium' HU with harman/kardon speaker/amp system. Pin-out is almost exactly the same as for recent model Toyotas.

UPDATED: Metra 70-1761 harness fits car's factory harness. That could be combined with a 71-1761 to make a "breakout" harness. Current version of the Metra 71-1761 does not fit without modification. The equivalent reverse harnesses from other manufacturers do fit (Scosche TA02RB, American International TWH-951). However, all of them lack wires on some of the pins Subaru uses.

UPDATED: I now have a combined "breakout" harness with these Toyota-style connectors available. Contact me by e-mail (not PM) for details. See the visitor message on my profile page here (click on my username).

9   [NC]  **
10  Illumination(+)

* Pin #8 provides power to Subaru's antenna booster amp. This can not be used for the remote trigger signal for a speaker amplifier, since it is only active while in AM/FM mode. On 2012-2014 Legacy/Outback models with HU with 4.3" display (which use Toyota-style harnesses), the power antenna lead is instead on pin #4 on the 6-pin harness.

** Pin #9 is an amp remote turn-on signal on BRZ; several Subaru models with Fujitsu Ten navigation and the factory harman/kardon amplifier and speaker system (2014-2015 Forester, 2015 WRX/STi, and 2013-2014 Legacy/Outback); and some Toyota HUs. On all other Subaru models, pin #9 is dead (no-connect).

The 28-pin harness is for BT mic, aux input, SWCs, reverse gear, VSS, and dimming cancellation. The connector is from the same family as the 8- 16- and 24-pin harnesses used for aux on other Subaru models/years.

* On some Toyota models, pin 11 is a ground used for aux enable.

** On Toyota GT86 HU TAS300 (and probably some other Toyota models), pin 13 is Aux Video Input shield/ground, and pin 14 is Aux Video Input (+) [not present on Subaru FT nav HUs]
On some 2015-2016 Subaru models, pins 11, 12, 13, and 20 are rear camera input.

6  Parking brake

7  Camera +6V supply (HU sends power to OEM Camera)
8  Camera Video In

15 Ground **
16 Shield/ground

** No connection is needed on this pin.  See notes below.

Impreza/WRX/STI wiring diagrams only show the parking brake lead and a jumper from pin 4 to 5 (not sure what that's for) -- no camera wires.

ADDED: On this HU, no connection to pin 15 is required. I previously thought this was Camera Detect input (similar to a pin on the camera socket on older Subaru models). However, this HU must see a video signal from the camera during boot-up, or it will not enable the camera function. Also, it North American models always add the distance guide marker lines. You'll need a camera that doesn't have those (or where you can disable them).


You can see a few more pictures on the FCC's site (for certification, since it has a BT transceiver). Go here:

http://fcc.gov/oet/ea/fccid/

then enter the 1st 3 chars and the rest of the HU's FCC ID ("BAB" and "FT0021A"). Several of the docs have pics. See the user manual for annotated drawing of rear connectors (but only limited info on operation).


Diagnostics Mode (UPDATED)

There are two trees of "secret" dealer setup menus. Access to both trees is very similar. Once you're in one, you can't cross over to the other -- you'll have to exit and start over with the other procedure.

Tree 1 (Line Diag, Audio Check, and Rear Camera functions):

1. Turn your key to ACCessory (no need to crank engine)
2. Let the HU startup (get past the screen with the "Subaru" or "Toyota" logo). You can skip the navigation startup screens by pressing the AUDIO button to switch to the audio screen.
3. Next, press and hold AUDIO first, then press and hold the other two buttons ('voice recognition' and MAP). The timing between them isn't critical, as long as you start with AUDIO and end up with all 3 pressed. An owner posted that he simply "rolled his finger down across the 3 buttons" (so your finger presses and holds each one in succession — top, middle, bottom). He said that works reliably.
4. After holding all of the buttons for about 3 seconds, you should see this "Line Diag" screen pop up:

   .
   (Click to see larger image. Hosted by ImageShack)

5. To exit the setup menus, press and hold either the AUDIO or VOLUME/power button for about 4 seconds, or turn off your key. The next time you turn on the HU, it will go through its boot sequence (which takes a little longer) and the navigation options setup (same as when you disconnect the battery). It still remembers your radio presets.

Tree 2 (Service Menu):

Procedure is same as above, except start with the MAP button. The timing requirement for when you need to hit the 2nd and 3rd buttons may be a little tighter for this tree.
On the Color Bars screen, you can touch each color to paint the entire screen in that color (pixel test). Touch screen anywhere to return to that menu.

See Lateralis' pictures, below.

Iam looking for months for how to get the multi function display to work with reverse camera. i have a subaru xv 2014. here in Australia, all the xv models comes with FT nav units with the reverse camera working. i have removed the mfd and looked for any pre-wired 8 pin harness. there seems to be none. i think they dont pre-wire for the models in oz. my plan is to install a non-rooted android tablet as my only multimedia device in the car. my reverse camera is now on the FT Nav HU. I understood the reverse signal 12V is sent to the HU on pin 2 of 28 pin harness and the thru the HU +/-6v on the pin 7/15 of the 16 pin harness to power the camera. The video signal from the camera is on pins 8/16 on the same 16 pin harness. With this understanding will it be easy to bridge the harness and send the video signal to the MFD for the reverse image. sorry for the long message. any advice would be of great help. thanks.

^^^ Good stuff. I'll let you guys know what I find out about the NC pins when I start messing with it. Should be getting the MS-8 in next week with some other goodies. Excited for my 1st 3-way system!

[Lateralis]

Now Regarding the "Diagnostic Mode". The way you listed SVXdc didn't work quite like that. Here's what I found.

1) You need to put the key ind and turn to the "ACC 2" position. There's 3 positions on the tumbler for acc. 1 does nothing that I noticed. 2 turns on the radio and the clock. 3 turns everything on.

2) Let the H/U go through its normal start up cycle. If you have the map selected hit agree and ok until the nav is up and running.

3) Press the Audio, PTT, and Map button at the same time and HOLD IT. PTT = Push To Talk so its that one in between the Audio and Map Button. It will probably go to the stupid voice recognition and ask for a command. If you did it correctly it will pop up the diagnostic screen in a second or 2. If not release the buttons. Let the H/U cancel the operation and try again.
4) To exit the Diagnostic Menu just turn the car off. When you start it back up it will take a couple of seconds to boot so don't wig out if it doesn't kick on right away.

The Following pics are of everything that I could do while in there which honestly wasn't much.

My Start up screen:




















As you can see I found no speaker test. Only thing it really lets you check is button functions of the H/U and SWCs, Touch screen, color, GPS, and allows you to update the software from there when need be. Interesting thing though is the Rr_CAM. So this means the H/U does check/have the ability to operate with a rear camera. Now we just got to figure out how!

[Lateralis]

Update:

So I got some new goodies in. Got the MS-8, PDX-M12, and the metra harnesses (Thanks David!). Decided to just use both of the PDX4.100's I have instead of getting the new PDX-F6. I'm going to use 1 4ch for the mid-ranges and tweets, than bridge the other 4ch for the mid-basses. I figured why bother amping rear fill so I'm just going to run them off of the MS-8 itself. You're supposed to get like 50W's out of it which should be more than enough.

I'm still waiting on my HAT speakers to come in and the rest of my wiring, so the weekend will be figuring out what I'm going to do for a sub box and amp rack. Contemplating using both W6's I have since the M12 is more than enough to run both.

[JebusTheGreat]

I have the same factory nav headunit. does it have a sub preout built in? I don't see a way to control the 'subwoofer' anywhere in the sound options.
