Do any of you know where I can find a wire diagram
I saw that one too. It looks nice, but is out of stock wherever I've seen it. Also not sure if it would fit in that spot, but I just figured I'd loose some trunk space. I've also looked at the 10" Rockford Fosgate all-in-one and the 12" which isn't much more money. I'll have to take some measurements and see how they will fit.I'm wondering how much space there is between the seat backs and the spare tire, under the carpet (where the emergency gas funnel sits). I'm almost thinking a long rectangular custom box could fit there.
Check out this process if you want the bass to keep increasing without dropping off. I did that awhile after adding my sub and it made it sound way better. I just did the one that disabled factory EQ processing.It is the nice and easy approach, and it hits good on 80+% of songs of varying genre, straight rattles the mirrors on heavy bass songs. The downside to me is the clipping is still a bit too noticeable. Without using an o-scope my ears tell me that when the volume is set at 15 on the Sony everything is great, turn it to 16 or higher you can hear the mid and high end continue to increase but the low end is flat and you can hear the processed signal from the LC2i just isn't as clean. I think I remember reading the LC2 cutoff was 1khz maybe? There are some lower end sounds from certain songs that just sound weird to me in that range. Overall it is a good compromise, leaps and bounds better then factory, but the sound quality does suffer.
Wow, I read most of that thread and I'm in way over my head. I don't have a Forscan and I really didn't want to invest that much just to improve the bass. I'm not really an audiophile, and definitely not looking to enter any SPL contests. How bad is the bass drop-off when just taping into the rear subs and running that into high level inputs to the amp? I'm sure there will be more distortion than using low-level inputs, but I've done that before and wasn't disappointed. There was no noticeable clipping. That was on my Ford F150 XLT that had complete shat for stereo. I replaced all of the speakers (JL Audio) and put a 10" Pioneer sub box in the back seat with a PowerBass amp. The head unit was stock and even though the results were not breath taking, it was enough of an improvement that I'm satisfied. I'm just trying to get to that point with the Fusion, and the Sony System is orders of magnitude better as a starting point than my F150. I'm happy with the Sony highs and mids, but it just lacks the bottom that I now enjoy in the F150.Check out this process if you want the bass to keep increasing without dropping off.

It is possible to reprogram the ACM to send out a flat line level out (approx 4 Volt preamp out) for sound out of the existing speaker wiring instead of regular high levels that are sound processed by the factory radio and/or Sony DSP (if equipped). This makes using an aftermarket Amp way easier as it will have the pure unmodified sound as if using regular RCA Pre-Amp Outs. Also makes for better audio tuning as the bass won't be cut off as the volume goes up on the stock configuration. This mod works on all Fusion ACM's, with or without MyFord Touch / Sony. Also allows for removal / disconnection of the Sony Amplifier in the back of the trunk.
This mod can be done with FORScan w/ODBLink MX Adapter:
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
* 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
