hey guys...

There's a guy on this forum selling 4 DX-6 Speakers. I want to spend as little money as possible, and see a good improvement in our stock system. I would like to upgrade the stock speakers, and put these dx-6's in replacement of them, but what else would I need to add to see a big improvement in virtually all categories? The speakers are costing me 100 USD shipped, and I will have someone in Toronto install them for me. What else would I have to get to get a really good sounding setup? I don't need something remarkable, but surely better than the bose that comes stock would be expected.

let me know guys asap.

thanks
