When I did the actual wiring, humming noise got cleared by itself.

For speaker pop sound, I read that I have to use some speaker protection.
Since I did not have the components, I added a switch for speaker.
I switch off the speaker before amplifier, and that cleared the popping sound.

Here is final build.
I am happy with the final outcome.
I used 12V 30A SMPS powersupply.
With right channel volume (inside amplifier trim pot) set to ~60%, computer volume at 50% and main volume 50%, room got filled with sound.
Right now, only one speaker connected.
Thank you all for helping.

speaker protection boards are easily available, all you need to do is check with your local neighborhood electronics store and you'll find something like this, but not as expensive though. All you would need to do is to find a power source for the protection board from your amplifier's PSU and run your left and right speaker outputs through it, to the speakers. Its as simple as that.

Very nice to see building with existing items especially for speaker outs. Well done. I have used Airtel DTH chassis for quite a few projects ( where smps were used) and it really worked well.

First day after the new setup. It went very nice. Meetings were so much easier to attend now. I regret, I didn't do it earlier.
Since I only have one speaker now, I placed the speaker back side middle 5 feet away for me. And it sounded really nice.
When I bring the second speaker, I will place them left and right.

I looked through and found this has good reviews. Cost only 260Rs
What I am not understanding is, in this where will I give the speaker in connection. The one which you linked clearly shows the IN and OUTs
Also this one support only 12V.
 
A beautiful, well-constructed speaker with class-leading soundstage, imaging and bass that is fast, deep, and precise.
