@JK Thanks man, The install has got some finishing touches to be done. I would post more pictures when it's done.
@Voila - Thanks, The amps are from Harman Kardon.

Largely tuning a mono amp is not much different from tunring a 4 ch. amp.
On the 4 ch. amp you would be setting gain and HPF freq,
On the Mono amp you would set the gain and LPF freq.
From the pics you posted I noticed that
a. the gain on the 4 ch. amp are at max
b. the gain on the sub amp is at minumum
c. the LPF freq on the sub amp is also at minimum (32hz).
this would mean that only information below 32Hz is being played by your sub.
you should raise the LPF freq of the sub amp to about 60-80Hz (between 9 o'clock and 12 o'clock).
you should then reduce the gain on the 4 ch amp to about 2 o'clock and raise the gain on the sub amp to taste (12 o clock might be a good starting point).

* When tuning what setting should be there in the Bass control remote?
* Should I make any changes to the phase setting, i've kept it at 0 now.

4-Channel Amp, both Front & Rear channels
Sub Sonic: Minimum setting (10HZ). If there is a way (a switch somewhere else on the amp) to turn this off, turn this off.
Freq: Set it so the arrow points at the 12o'clock position -- More on this later
LP/FLAT/HP switch: Set this to HP
Gain: Set it at 50% (12 o'clock)
LEFT/STEREO/RIGHT switch: STEREO
FRT/REAR/SUB switch: Set the Front channel to "FRT" & Rear channel to "REAR".
Sub-sonic: Minimum setting. If there is a way (a switch somewhere else on the amp) to turn this off, turn this off.
Freq: 80Hz (Max. position).
Gain: Set it at 50% (12 o'clock)
- Switch all boots (bass, loudness, expander etc etc) to off.
- Switch the EQs off or set them to FLAT.
- If there is a DEFEAT option, turn that on.
- Set Subwoofer Level control to about 60-65%.
- If there are Crossover settings,
- In the Front Channel, set HPF to ON, and Frequency to 80Hz
- In the Rear Channel, set HPF to ON, and Frequency to 80Hz
- In the Subwoofer Channel, set LPF to ON, and Frequency to 80Hz
- Pop in your favourite CD and select your favourite song. Play it.
- Increase the volume to about 50% of the maximum.
The sound should sound pretty good now.
- Now go to the amp and adjust the GAINs of all channels (up or down) so that this volume level (of the HU) is your "medium-volume" or normal listening level.
- Next, sit in the driver's seat and adjust the gains of the rear channel so you can just barely hear the rear speaker playing.
- Slowly increase the volume till it is maximum, or till some of the the drivers start distorting.
- If the volume goes to the max without the drivers distorting, you can either leave it as it is (if you will never listen to music at this high a volume). If you are likely to listen to it even louder, increase the gains of all channels (in the same proportion as before) slowly till one of them distort. Dial back the gains till the distortion goes away.
- If the sub distorts, dial back the gains, and then check with the Subwoofer Level (in the HU) at MAX. Adjust the gains so distortion goes away.
- Go back to the normal listening level in the HU (and 60-65% Subwoofer Level) and see if all the drivers are balanced (rear's can be just barely heard, sub does not overpower the other speakers etc.).
If all is ok, you are about done. If all is not ok, adjust gains in the amps so all is ok. You can dial the sub to the level you like it at (from the HU).
You can fine tune the crossover attenuation levels in the HU (if you have that facility) to further adjust how the setup sounds.
Try how the overall tuning sounds like with 3-4 CDs till you get a level of tuning you like
BTW, the Subwoofer Level in the HU is to be treated the same way as external sub control modules. I personally don't like using the external modules as well as the HU Subwoofer Level control.
This is how I like doing the tuning. Try it and see if it suits you. I'm sure some of the gurus will also post instructions to help.

Thanks a lot Hydra, thats someting a person of my sort can understand easily. The instructions given by you and Navin is really helpfull. I'm taking a print out of this whole page. I will tune the amplifier tonight or tomorrow and will get back here with what I got.

Thanks AG, First I myself should find some time to look at my amps during day time. There a few things yet to be done like getting a replacment rubber mat for the boot, tuning and so on. I would post some nice pics when I'm done 100%. I'm thinking to bunk office for doing these.

Mods could you change the title to something like "My Fiesta 1.6S + Harman Kardon + Infinity Kappa + Image Dynamics"
