I agree, this is an incredibly stupid way to reset the Sync system but what to do, this is the only method which seems to work. Some Ford users in US had created a Sync Reboot bootable USB utility but it doesn't work on the Indian version.
Coming to some simple speaker upgrade options:
First about the OEM 4 channel amps and the stock speakers -
The Ecosport system deploys a Sony Class D 4 channel amp and delivered approx 18W / channel in my setup. The chip set used is a fairly decent one and can be found in some of Sony's Class D based HT A/V receivers.
The only issue which this amp has is that it is highly dependent on a high rail voltage to deliver its best and the current delivery is average at best. (yes I actually took measurements and had opened up the system - blame it on an itchy DIY mindset
)
What this means is that one should take efforts to keep the battery fully charged up in order for this system to sound its best. Road tested over 1000Kms by me.
Another issue with stock speakers is the issue of a non existent sound stage (its near the knees) which causes recordings to sound weird, although there is a DSP which alleviates this problem to some extent.
Once tweeters are added in the position provided in the front doors, the soundstage improves massively and one can immediately notice the real sound quality these Sony amps deliver.
Adding just a pair of tweeters is therefore the simplest speaker upgrade. Suitable 0.75" and 1" options are available from Hertz and Polk Audio and the estimated spend is around INR4k. I have a slight personal preference for the Polk Audio tweeters.
Second upgrade option is adding a set of 2-way and co-axial aftermarket speakers.
The Sony amps are inherently bright so they mate well with a slightly darker or warmer set of speakers. The poor current delivery issue can be mitigated by choosing a high efficiency set of speakers, ideally above 90dB/W/m sensitivity. This spec can be easily read off the speaker specs of most mainstream brands.
Based on the above, I had narrowed my choice to two specific 2way speaker systems which I could audition first hand, Morel Maximo 6 and Focal PS 165.
I found the Focals to be louder, brighter and a better soundstage than the Morels, but knowing my personal preferences and the fact that this kind of sound can cause listener fatigue over extended sessions, I went with the Morels.
For passenger doors, go with a matching co-axial speaker system.
There will of course be more choices in the market, just keep the above in the mind while choosing yours and make sure that the speakers are spec'd to be driven by factory/OEM amp systems.
With this upgrade, the system can go as loud as approx. 90dB in drivers seat at the 18 or 20 volume position which should be loud enough for most listeners but it is definitely not ear bleeding concert level loud. The bass frequency response is good to about 70Hz or so and then it starts dropping sharply.
One should definitely use a MDF baffle ring to mount the mid woofers and although the door is well damped, do go for additional damping from Focal or Dampmat etc. This will have some benefits in enhancing the mid range sound quality. Use of good quality speaker cable is also recommended. 16AWG is more than enough for this application although one can go as high as 14AWG. Try to use a thinner 22AWG for tweeter connections, this is to alleviate skin effect related performance issues.
I think this is a long enough post, in next instalment I can share about additional mid-range/tweeter install locations and active woofers etc.
