So maybe one of you guys can help me here. Last weekend I installed JL C3-650's in the front, C2-650's in the rear and 2 10TW-3 subs with RD amps for 4 channel and mono. I also had an LCQ-1 installed. I usually do my own installs but this time I didn't. My issue I'm having is that I am getting really loud hissing, and if I turn the gains down on the amp on the LCQ to eliminate it, there is not nearly enough volume. Also, changing settings on the LCQ literally makes no sound difference. The only ***** that make a difference are the main channel ***** on the LCQ.

So I have FORscan and tried flattening the equipment, but when I do it, I lose all sound except my front center speaker which I'm assuming is because it's just not hooked to the amps and is still running off the stock unit. I guess I'm confused on what to do to get more volume without the hiss, and try to figure out why the eq adjustment ***** on the LCQ aren't making any difference. Anyone have any advice? Thanks in advance!

Sounds like you changed the Outputs to low level. To flatten the EQ only, you just have to change one number to a "0" in the ACM. I'm trying to find my post on which one that you need to change.
Found it.
With forscan also flatten the EQ output from the factory radio and make everything sound better to start with.


FORSCan codes:
ACM
727-01-01 xx5A xxxx xxxx This one makes the factory outputs a low level for an aftermarket amp.
727-01-02 00xx This one flattens the factroy EQ.

I'm waiting for the Rockford Fosgate DSR1 to come out.

I just put in a new system that uses a PAC Pro amp module that allows low level rca output from the SONY HU ( it is not a LOC).
The Sony AMP is no longer feeding my speakers, this is done with an aftermarket amp.
But I want to flatten out the factory EQ using this....correct?

With my setup the Sony amp needs to stay in place just for the HU to "talk to it"
Do I still need to do this APIM part? Not sure what you mean by " disables Sony sound processor"

"If it's a Sony system, this would need to be done in APIM also:
7D0-01-01 2xxx xxxx xxxx - disables Sony sound processor"

So I finally got around to putting all my stuff in and went with the JL FiX option. It worked fine and all but if you didn't use the remote volume, it got kinda noisy....probably not for the average Joe but for an audio snob like me, it was too much. The remote volume worked very well but at the end of the day, it was not as convenient as using the factory controls. There really isn't a good place to put it where it's easily accessible. Plus, I like having actual numbers and clicks for my level controls so I can have a reference point for tuning.

So I broke down and used the Forscan method and I've got to say, this is without a doubt the way to go. No noise, factory controls work just as they always did and with the Parrot wiring harness and the Stinger 9 wire, wiring was pretty simple. The only thing I kinda lost was my backup alarm. It still drops the volume of the music and plays the tones but they're a lot quieter now. I only used the front channels as inputs to my TwK processor so if I had used both front and rear, it would work normally as it's the rear channel that the backup alarm tones come through on.

So yeah, in my opinion, this is absolutely the best way to go. Takes an investment of a OBD Link tool ($80) and some time but that's about it. You have RCA low level outputs from your stock head unit while retaining all your factory controls, features and looks. Once you figure out what to do, it takes literally like 2 minutes to make the adjustment in Forscan. The biggest pain in the nuts for this whole thing was trying to get the OBD Link to pair with my laptop.

Like 1NiceHarley posted, these are the codes you need at least on 2016 and later models. The ones on that Fusion page didn't work so I'm guessing Ford changed some programming in years after that thread. I took a picture of the original programming with my phone so if I ever need to go back to stock, I can just plug those numbers back in.

FORSCan codes:
ACM
727-01-01 xx5A xxxx xxxx This one makes the factory outputs a low level for an aftermarket amp.
727-01-02 00xx This one flattens the factroy EQ.

Can someone document the wiring when you do the Forscan option? I understand the programming part, but I believe you have to cut some wires and solder on some RCA's... I've never seen pictures of how that's done and where those cuts are made.

Thanks.

Upgrading the audio in my 2016 f150 xlt with 8 screen and nav. (Not Sony) I have a mono amp and a 12 inch kicker installed. I have kicker door speakers otw. Not sure if I will buy a 4 channel amp for them or not. Assuming I have 2 amps pushing the speakers and sub, will I need to flatten the eq or just use the code to lower the speaker level output? Will the eq still work?2..I'm assuming that if the signal isn't going to an amp then I shouldn't lower the signal level or flatten the eq??

Shelbie67

anyone? Would love to see the wiring so I can remove my Sony paperweight...

Is there low level signal output from the factory amp? If so, can you just daisy chain an aftermarket amp to it, and retain the nav/sync/chimes?
