@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.

The 4-channel is actually taking over the mono. Also there is a change in the way the 4-channel sounds. There are lot of options in both the amplifiers which i'm not able to understand. I can understand setting the gain part but it would be really helpful if someone can explain me in a simple way what the others do (Especialy the Sub-sonic part) or atleast tell me which would be the best.

I'm giving the pictures of the tuning options present in the Amps. I can understand what they do from the amplifier manul, but I do not know which would be the best setting. My question may be noob, but i could use some help here. I do not want to go to my installer for getting it to sound the way I like it, He does tune it the way i want but that is only if i explain him what i want, that i'm not able to tell him. I would love to know how to tune my equipment.

[quote=sathee46;1318604Please gurus help me with my above query.[/QUOTE]

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).

I would suggest setting the LPF/HPF at the HU.
32Hz LPF?
Please don't let the installer do the tuning. He only knows tooning.

Thanks a lot for the reply Navin, the pictures i have posted are of the brand new amp before install. This more like the way i can understand, I will try the settings as advised tonight. What shall I do about the subsonic part, any easy advice on that too? i will give you a better pic of the mono. (Even the 4-channel has a subsonic filter)

i'm getting a multimeter to try some tuning as given in the gain settings simplified thread. Hope I dont end up tooning.


Edit :

* 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.

The 4-channel
Attachment 139469

The Mono (The part marked DBO in the below picture is marked as Sub-sonic in my amplifier)
Attachment 139470
To start with, try the following settings:

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".

Mono Amp
Phase: 0
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)

HU
- 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 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.

Yeah it sure has. I've not changed my compos bro, it's just the mono and the sub which is new to the setup. I would give a detailed report on the whole setup once i sort out the tuning issues and listen to the setup for a while.

Hmmm, I was wondering how to do that myself .

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