I need some advice on stting up my stock "premium" headunit to upgrade from a single cd to a 6 cd changer. My "new" Subaru headunit is a P128 am/fm/wb/6cd bought from another Subie owner. It plugs plugs right in and the 4 speakers do work ok.

I am new at this and have connection questions on adding a subwoofer (not the underseat one but one in the back):

1. I see picture of a 8 pin plug for a subwoofer. I need a plug for this if I am going to use it. Anyone take theirs out? Can I just add the 2 colored wires or do I have to make a grey loop for 2 pins?

2. What quality of signal comes from the 8 pun plug and how low does the sound go from this plug?

3. Is it better to add a amp to the current system through the speaker wires and ignore the factory square sub plug for better sound?

4. If I add a aftermaket amplifier for a sub in the back - by connecting the speaker level inputs to my stock speaker wires will it affect my speaker volume?
does it "suck" away power from my speakers?

My idea was to use a very sensitive subwoofer with the original outputs to save money and wiring if it will work. Alternate idea is to use a small amp with speaker level inputs to power a subwoofer in the back if that is necessar for full range subwoofer sound (if it will work like that).

Default 35th Ann. Ed. wood trim removal

How do you remove the wood trim panel in the 35th Ann. Ed? There are ones that run along the top, but the bottom is attached to something, or clipped somewhere, that I can't find. I've pulled off most parts around it, but can't get the wood trim to budge. Any suggestions?

1. I can make that 8-pin harness. Contact me by e-mail. On certain Legacy/Outbacks, the loop wire connects to the pins for the Onstar audio input. But it occurs to me that on other models it may enable the sub output.

2. I'm not sure about the P128 radio, but in others the sub out is either a 20 Watt or 65 W speaker output, fed from a mix of the four main speaker signals (before they go into the 4-channel amp IC).

I seem to recall reading a post saying that the frequency range doesn't really go ultra low. It's more of a low bass than a true subwoofer. Why don't you hook it up, burn a sweep test CD (images are available on the web), and tell us how it sounds?

3. If you want a really loud, rattle-the-windows thumping sub, you'll almost certainly need an external amp. It may still work to drive that from the sub output on the 8-pin socket. But you might start with connecting a good sub speaker directly to the sub output and see how it sounds.

4. An aftermarket amp connected to the HU's speaker outputs should not noticeably affect the sound coming from the main speakers.

Do you know which year/model that HU came from?

What year and model is that? Pictures?

Added: Sounds like the 2004 Legacy L 35th Anniversary edition. You'll probably find tips on LegacyGT.com, LegacyCentral.org, or SubaruOutback.org

Radio trim removal tips here: http://www.butkus.org/subaru/outback...ack_stereo.htm

To continue the stock rear subwoofer exploration:
AM/FM/WB/6 CD Changer is a 2 Din single unit P128 from a 2003.

I could do a test CD to check out the response once I have the plug wiring and sub speaker ohms resolved.

Need help here- someone with a non-mcIntosh system to look at the back of their rear panel sub-speaker (in the right side panel opposite the jack) and see how many ohms the stock one is. It would need to be pulled out to look at the back. Also need the speaker wire colors. I tried connection to a purple and white wire plug in the back but had no sucess.

I think I can mount a 8" or 10" speaker in that area which might go lower than the stock 6x9 in the back.

I hope I'm posting in the right area...
Ok, heres the problem-
2 days ago my stock 6 disc changer in my '07 impreza stopped working.
I was listening to a cd and wanted to change it to another so I pushed the #2 button.
it tried to load it but couldnt.
then it told me to press eject.
I did and I could here it trying to do something but it couldnt eject either.
No other cds will load or eject.

My AM/FM works and so does aux; its just the CD that are giving me problems.

any help is appreciated.

Sadly, that problem is all too common -- the 6-disc mechanisms like to get jammed.

If your car is still under warranty let a dealer replace it. There's actually a procedure where they'll ship the HU to Japan, extract your CDs, and ship them back to you.

if your car is just recently out of warranty, you can try calling SoA and politely appealing to have it fixed for free or a reduced charge.

Otherwise, you'll need to do some surgery.

You'll probably have better luck finding pictures from older threads on SubaruForester.com or ScoobyMods

If your car didn't have the rear cargo sub from the factory, then the wires may not be complete all the way between the HU and sub. I'm not sure the plug and wires at the sub will even be present -- if you're seeing a plug there, it might be for something else.

hi all, i'm having a rockford-fosgate p400-4 and boston acoustics sl65's installed in the front doors with the existing h/u on a base 2010 wrx, leaving the oem rear speakers in, but amping them. is this a fairly straight forward install for a qualified shop using line connectors to connect the amp? tia

Yes, it's a straightforward installation. Since the Rockford Fosgate P400-4 does not have speaker-level inputs, the installer will need to add a 4-channel Line Output Converter (LOC) to convert from your HU's speaker outputs (high-level) to send into the amp's line level inputs (RCAs).

Then they can either connect the outputs from the amp back into your factory speaker wiring, or run new speaker wires from the amp directly to the speakers.

Unfortunately, none of the aftermarket harness manufacturers makes 20-pin Subaru harnesses that include all of the pins/wires that OEM Subaru HUs use. So an installer is going to want to cut your factory speaker wires behind the HU to "hard-wire" the LOC . To return to stock, you'll have to reverse the procedure and splice the factory wires back together.

For more info/tips, see the 20-pin harness pin-out here (post #11 in that thread), especially the "notes" section below the table.

For the non-Navi OEM HU, the only choices are:
  1. Use +12V Accessory. That will activate the amp whenever you turn on the key (whether or not the HU is on)
  2. Add a remote trigger module -- senses signal on a speaker line and generates a +12V amp remote-on signal

The OEM Navi HU has a pin for amp remote-on. In Imprezas, that pin/wire is not present -- you would need to add it to the factory harness.

And please do not cross-post (especially not 6 times!). You risk getting banned. Post a question in the ONE, most-appropriate thread.

The on-screen controls are for the subwoofer output on the 24-pin Navi harness. That ouput is only used in some Foresters, for a powered sub in the rear cargo area.

You'll need to add pins/wires to the vacant positions on your factory Navi harness. See the pin out (bottom half of post #11) for details. I actually now a cable with RCA jacks and the appropriate pins to do that. E-mail me for details (click on my username).

I'm fairly certain that grounding pin 7 enables the sub output. [Update: This is not correct. Pin 7 does something else. The sub out works even with pin 7 disconnected.]

Pins 12 and 24 are a balanced (positive and inverted components of a) mono, line-level signal. Pin 11 is ground.

Pin 23 is the amp remote-on.

I'm having a deja vu moment here (although, admittedly I've kept adding info to the pin-out since then).

So I read about the 08's being bluetooth enabled but not having the microphone. My car does not have "Phone" in the Menu of the navigation screen, it just has the "Stored Locations," "Navigation Set Up," "Route Options," and "Version" in there. Will it automatically recognize the mic connection and add this or am I need in need of a software update of some sort?

Edit: Found out that it will add it once the mic is connected.

hello, i tried searching but maybe you can help me out sir...



I have a 2010 sti with factory nav, what do i need to do to bypass the e-brake so i can watch dvd/ input address, i read # 4 as ground? grey wire. what do i do with it?

also would the e brake light be on? if so what do i need to make this go off?

would DRL be off if the above modification made? if so what can i do to keep drl on and the function of the bypass working at the same time?

thanks

If you simply ground the wire, then yes, your parking brake light will be stuck on and the DRLs will be off.

What you need to do is cut or de-pin the wire going into the Navi, so you can ground that pin without grounding the rest of the parking brake circuit. Note that the pin 4 wire may not still be gray on 2010s.

However, I've read posts saying that the Navi will detect motion via the VSS wire and/or GPS, so it may still lock out certain menu functions once you're driving, even with the parking brake pin grounded.

Is it true that there still is no 'smart aux' to trick a HU with the rectangle, 16-pin connector for the 6-CD changer, into thinking a CD player is present when it isn't? Is it as simple as post #3 suggests? Sending +5VDC into pin F (pin 6)?

None that I've heard of. The problem has always been that nobody could find an OEM external CD changer to plug in and "sniff" the protocol.

The hack mentioned in post 3 of this thread is on the round CD deck jack found on older models (early 1990s). The hack is detailed towards the bottom of this page. The HUs this worked on typically had AM/FM and cassette in a 1-DIN unit, and an optional CD player in a separate 1-DIN unit that connected via this socket.

Later Subarus (not sure exactly which years) use a similar round socket but switched to a digital data bus, so the hack described on that page won't work on those years. These decks usually had a CD player built into the main HU, and the socket was for an additional, external CD changer.

Bit of a long shot this one but......
I have a 2009 standard Nav head unit. I want to fit headrest monitors so the kids can watch DVDs whilst on the move and would like to use the Nav DVD player to drive the additional monitors.

What I am wondering is, could one of the pins (marked as not connected) in most of the pin out documentation found on the web, actually be video out?

Has anyone been able to get a video out feed from the Nav head unit?

Many thanks in advance for any help offered.

What about any audio in for 08MY Forester Kenwood GX806EF2 (service manual) radio?

Front:


Back:


I found what this HU used by FHI with OEM European navi like on this picture:


So, audio in is available.
But how navi connects to radio, what a part number and pin-out of this connector?

Thanks!

Thank you for the link to the service manual!

The navi connects to the 20-pin socket. The pin-out is the same as in this post (post #8).

The navi (or an external CD changer) uses a data protocol to command the radio. We need to learn that protocol to be able to "trick" the radio into turning on the external audio input. Nobody has found a Subaru CD changer that we can obtain so we can decipher the protocol. Sorry

This device, FSL-21 (successor to FSL-01), might work (price ~ $200 USD). Also see here. Or it might not be compatible with your radio.

Thank you for fast reply, SVXdc.

Another link for third picture (Kenwood GX806EF2 + Subaru OEM European Navi)



FSL-21 price is too much, unreal! Used HU in condition like new is about 50 USD.

So, it's no way now to use this audio in without adapters like FSL-21?
I want to connect hand-made navi and need any audio in. Its not a big difference in channel count, mono or stereo.
