So one thing for sure is that there is some issue with the right channels.Can anyone help me out what can be the issue?Is it a wiring problem or is the HU itself is a gone case?Please please guys, help me out..
The volume was set in between 22-32 and in the whole range I could hear the clipping |

Kaushik, it is higly unlikely (though not impossible) that the HU is at fault. If the source was Blau and not the Kenwood, and the Blau is the culprit, it would be easy to get the HU repaired.
But first overrule all other possibilities of causes. I think it is time for you to use test tones to isolate the problem. There is a fairly recent link where someone has found test tones; PM @clipto333 - he would be able to point you to the link if you don't locate it. Test tones, since they are single frequencies, are easier to work with when tuning / debugging, since you wont be misled by interference in normal music.
- Keep the balance and fader at 0 so that the HU puts equal signal in all channels
- Now slowly increase volume playing a 1KHz test tone repeatedly. If now you hear clipping only in the R channel before you hear it in the L channel, HU maybe suspect - cross check: with a slight shift of the balance to L, the clipping should vanish (or not, HU fault in that case)
- If clipping occurs in both L & R at the same time, HU is not suspect
- If it happens only in front and not at back, or vice versa, quite likely the corresponding speakers are suspect
- If no clipping occurs at 1KHz till a comfortable volume, test at gradually lower frequencies till you hear definite clipping
- If that doesn't trap it, go higher than 1KHz step by step
The decision logic would be the same in the above cases. If it cannot be isolated to wiring or speaker faults, the HU needs to go in for service.
