I'm very familiar with FORScan. Do you mind sharing the module you changed? You seem very knowledgeable. What are your thoughts on changing out my doors speakers to JL Audio C2-650 component front, & c2 coaxial rear powered off the factory amp with DSP change. Then swapping out the sony speaker with a different brand in the factory enclosure?

 

Gabar, you could PM me as well, if you don't mind.
Much appreciated.

 

 

I honestly think any money you spend on top of that Sony DSP is just throwing good money at a bad solution. I think you'd be waaaaay better off ditching the stock DSP all together and using an aftermarket amp. You can disable the DSP alone so it gives a flat signal, but you'll have little control over time alignment if that's important to you. I'm happy I didn't have to deal with the Sony in my truck, it was much easier to upgrade, but its not that difficult if you want to. You can disable the DSP, and convert your output from your headunit to be a 4v low level signal. Just use a harness to plug into your head unit and run the RCAs to your aftermarket DSP or amps and you're good to go. Below are the options to do these various things in FORscan.

727-01-01 xx59 F8x8 xxxx - Enables Line Level with Optional Subwoofer (Aux 1) and Front Center (Aux 2) Outputs Enabled*
727-01-02 00xx - Disables Factory EQ Processing
(ACM As-Built)

* This string breaks down as follows:
5 = Variable Line Level Audio Output
9 = Enable External Subwoofer (AUX 1) and Internal Amplifier (Aux 2) (0 - Disable)
F = Disable Open Speaker Circuit Detection (w/Active FM Radio Antenna - Otherwise use a D)
8 = Front Tweeters Present
8 = Aux 1 Type: Mono Subwoofer and Aux 2 Type: Front Center


7D0-01-01 2xxx xxxx xxxx
(APIM As-Built) - APIM change required only if you have Sony DSP before completing this mod.

 

I'm honestly thinking just replace everything. Tap off the speakers at the amp in the rear and enter those wires into a JL FiX86. Remove the Sony sub entirely. Then adding a XD700/5v2 amp with some C5 components in the front and C5 coaxial in the rear. As for the sub, I would fab a small enclosure to house a single JL 10TW3-D4. I'm not sure where I would mount the crossovers yet. I like everything to be hidden and look OEM...

 

That system would be 1000x better than what comes from the OEM. If you're into quality music at all I think you're on the right track.

 

Does anyone have a door panel off photo? I'm not sure if my front doors house 2 or 4 speakers. I'm being told if I have the sony system "which I do" then it consist of 10 speakers. "I should have a 6.5" sub and a 4" mid in each of the front doors." Just looking for a little confirmation while i'm traveling and have no access to my truck at the moment.

 

You have 6x9s in the front doors and 6.5s in the rears. No super duty has ever had a 3 way component system in the front doors that I know of.
