Rally,
Use a 3 pin to 2 pin adaptor,it will solve the issue,your laptop itself does not have a ground as its input is dc ,the power brick in some laptops also comes with a 2 pin plug.

Nice work!! Now don't get overconfident... Else you will catch your friend for humming a tune ... Shove a wire up his nostrils and connect it somewhere to "solve" his humming problem!!!

Cheers

Hi Sandeep,

The bass is surely not comparable to the high end subwoofers costing way above 20+ INR, but it will serve the purpose and will be an upgrade to the mass market music system bass response.

use high quality subwoofer cable especially those made only for subwoofer and one more thing u do as i did was ground loop ur house circuit ,what i did is i have little garden in my house and in it i hired some guys who dig 25feet underground and in that i put 6inch copper piece ,5kg of black salt and 5kg of wooden coal (i mean coal we get after burned wood pieces) and i pore water in it compeltely and i use 25feet metal rod ,in that rod i pass 35 feet of copper wire attached with 6inch of copper piece and fill it with 5kg of black salt,5kg of wooden coal not pieces but in powder form and water lots and lots of water ,purpose for water , salt and wooden coal is to make underground portion wet which helps is maintaing earthing (35 feet copper wire coz 25 feet for underground and 10 feet distance from my main house metre)

i hope u understand what i;m trying to say my english is not that good , b4 that when i don't earthed my house i have humming from my sub and also from amplifier but now no more humming :yahoo:
whole material and labour (for digging ground) will cost u 2 to 2500 rupees

Digging a earthing pit while living at the 5th floor of the building will be quite a thing hyeah:
I think this temporary solution works for me, Moreover, I am not using the sub, so doesn't matter to me anymore.

ground loop ur house circuit ,what i did

I understand the earth pit. In fact I have 5 of them around my house for my mains incoming, for the general house wiring, one of my radio equipment and for the hifi. But what is the deal with the ground loop? I will try hardest to avoid a ground loop, not to make one
