Default "True" Remote Out Line? 08+ WRX

Ok, so I installed an AudioControl LC2i and a 4 channel amp to power aftermarket speakers in my 2009 WRX w/OEM nav. I used pin 23 on the 24 pin harness for my "remote out" to turn on the amp (I know the LC2i)
itself acts as a remote out as it turns on when it detects sound, but using this, there's a loud pop when you shut the car off, and the problem I'm about to describe persists) but when I turn off the head unit, the amp stays on. Theres no music, but you can still hear "sound". So basically, pin 23 amounts to a 12v power source. If I run the remote out from the LC2i, same thing, the amp stays on when the stereo is off. It would seem the speakers are always "active". Anyone else have this problem and if so, what did you do?

The ghetto fix would be to install a switch on the remote wire and turn it off manually, but I'm not ghetto. Any ideas?

Thanks in advance.

.... didn't think so....

Guess the only solution is to replace the factory nav. Gay.

Seems like you have the line out hooked up to 12v constant.. Try an accessory wire. (12v with key on)

I have the LC2I but used one of those breakout harnesses and it works fine, no popping. I'm guessing the previous poster answer is the issue.

Fwiw, the $40 breakout harness makes installs so much better.

I have the line out hooked into pin 23 on the 24 pin OEM harness....it's empty from the factory but can be used for a remote wire for a sub amp supposedly.

I used the SVX breakout harness for my install to wire the LC2i, but that's not the issue.

The real question is does anyone know of a wire from the factory harness that provides switched power when the audio is on, but not when it's off?

Not like it matters terribly anymore, I ordered a Pioneer AVH3400BH this morning as I'm not going to be driving around with the stereo always on and a factory nav that can't find 500,000SF high rises in Chicago (seriously... the factory nav says 220 N LaSalle in Chicago is an "invalid address"..... I'm looking right at it!!!!!).

You have a grounding issue and/or your gain is too high. If you're using the FW602US make sure the secondary gain is not above around 10. Also I'd recommend getting an add-a-circuit and pinning it to an ACC lead in your fusebox. That should solve your power issue.

Popping issues are typically a grounding problem so double check the wiring to your aftermarket speakers. Are you using the OEM wiring or did you run new speaker wires?

No grounding problem. The amp is grounded to a sheet metal screw on the fllor pan and the LOC is grounded to the headunit. I replaced the interconnect and there's no popping anymore.

The speakers have been rewired.

The gain on the amp isn't even 1/4 turn up and the gain on the LOC is set in the middle detent. Neither of those things are my problem - the problem is there isn't a source for a true remote line in the back of the facotry deck. Even if I used an ACC source for 12v, it would be on when the car is on, independent of when the stereo is on or off, which is what I'm trying to prevent.

Thanks for brainstorming, but it doesn't sound like there is a real fix for this issue. Oh well, new deck should be here by the end of the week. Now if I can only get SVXdc to respond to my new order request......

TheRzza has a 2009 with the older OEM Kenwood Navi HU...



The issue is what happens while your ignition key is on (either ACC or ON) but you turn off the HU via its power switch ("AUDIO OFF" mode).

I've checked this on a Navi from a 2009 Forester (model number FXDD07KF2) and confirmed that the amp remote turn-on lead stays on. In other words, it's on the entire time the HU has +12V Accessory. TheRzza wanted his sub and speaker amps to shut off when you switch off the HU (like most aftermarket HUs do).

The Kenwood Navi HUs in 2010-up cars are a different model number. It's possible the amp trigger pin could work "properly" on those, but I don't know. We'll need someone who owns one of those to check. Incidentally, the Navi also leaves the power antenna control lead on even when you're not in AM/FM mode. Since some versions outside North America have the traffic data feature (RDS-TMC), I'm guessing it does that so it can still receive those signals.

(and order has been reply to and shipped -- harnesses and parts to replace the Kenwood Navi with an aftermarket HU)

ADDED: Just occurred to me -- it probably leaves the amp trigger on because even with audio off, you could still need to get sound from the navigation prompts. Also from Bluetooth phone calls (if that works during 'audio off' mode). Incidentally, it also leaves the power antenna control lead on even when not in AM/FM mode. Since some variations outside North America have the traffic data feature (RDS-TMC), I'm guessing it does that so it can receive those signals even while in 'audio off' mode.
