1. Check if any of the speaker terminals / wires are shorting (with each other or ground; check with multimeter, with amp off)

You guys were absolutely right. It was a case of speaker wires shorting with each other.

So i have removed the face plate of my HU & kept it at home until I find time to resolve these issues. Will get an update as soon as I fix them.
cheers

And the reason for the same is RATS. I had parked my car for a couple of days in my office forgetting the rat menace in that area. In fact, now we are spending 80k a year to keep those rodents at bay.

Nope, my SONY is fine, thanks.

Even i had the same issue with my 75.4 for front right channel but sorted out with my installer as one soldering was not perfect and it keep on loosing the contact after heating up after 10-15 minutes usages, he took 2 hours to trace down the location and again done a soldering job and it started working fine.

Yikes, seems then the cat nap in the hammock pic is appropriate. May I now suggest a BB gun...
