Hi All,
Just added rear speakers to the stock K10 AMT unit. I didn't purchase these speakers and simply removed them from my old Alto K10 and put them into the AMT, albeit on a new MDF board. Just a brief flash-back on my ICE installation story!
When I visited my usual accessories guy, he said that its impossible to fit rear speakers separately onto the K10 unit (Nippon NC67P0) as these low cost units do not offer a separate rear channel and that they are built to cost. He even went on to say that these units barely cost 800-1000 rupees and they are worthless. He offered to connect the speakers to the same channel as the front (stock) speakers, as in, drawing a parallel from the speaker connections. This meant two things - I'd lose the ability to Fade music between front and rear speakers, and more importantly, output would suffer. Despite double checking this with "Mr. Adamant Accessories" (lets call him Mr. AA) he flatly refused to do the connections in any other way, giving excuses that the front panel housing the ICE will crack and break if he tried to open it. In fact he also persuaded me to upgrade the system to a single/dual din unit which would have separate channels for front and rear - but he would not open my stock unit, not even to check! That may be his opinion and I thought differently.
Cut to the chase - and I come across TBHPian Torino's ownership review of the K10 AMT. Even he was on the lookout for a decent ICE and didnt want anything too fancy. He also directed me to his post on his ICE setup where he added rear speakers and tweeters.
After getting further info from Torino and making sure that the rear speakers CAN in fact be fitted to the stock unit, I decided to challenge Mr. AA! Armed with this info, I met Mr. AA again and he wouldn't have a word of it - he was adamant that this unit cannot have a rear output. So be it! I left without saying a word as I knew it could be done.
I tried my luck at another accessories place, but this time, one which was listed on the TBHP Directory listings. The place is Konarks in 9th block Jayanagar. I met "Gurudev" and told him about my dilemma. 10 minutes later, his boys are working in the car, fitting the speakers!
Fast forward 1-2 hours and the job has been done. I now have output on all 4 speakers and I couldn't be happier. Job done, $$$ saved!
I have clicked some pictures of the installation. As I had requested not to cut any wires, the boys at Konarks did a wonderful job rummaging through their "spare connectors" box and finding a plug-type bracket that fit the stock Nippon Unit. They then did the wiring and everything worked perfectly without a wire being cut. Total damage: 850 Rs (as I had my old speakers with me)!

^^This is how the stock unit looks when the outer trim is removed. Use a screwdriver and pry open the piano black trim from the steering column side.. it comes off cleanly and only thing holding the trim are 4-6 snap-on clips. Once the trim is removed, remove the 4 screws as indicated to pull out the stock unit.

^^Notice that the pins are very much there for rear channel out at the back of the unit. If there were pins missing, Mr. AA would have been right. Take that Mr AA!

^^They finally found a matching socket connector.

^^And the wiring process is almost done.

^^Wires attached to the unit. The open end of the blue plug connects to the stock wiring kit that comes from the manufacturer. The loose Grey and Yellow-White Wires connect to the rear speakers.
Many thanks to
Torino for giving me the right information on this setup. Else, I would have become a scapegoat and would have probably bought a new unit from Mr AA.
