yamaha yht-150 should i keep?

so i just came back from shopping and bought a yamaha yht-150 ... it was pretty cheap at $150. I'm wondering if i could get a better system at that price or should i just keep it... i'm hesitant on opening it... i can't really find that many reviews on this set on this forum... but on amazon.com they think its pretty good.


i have a room thats no bigger than 12x12 and theres lots of stuff already in it (ie computer tables and cabinets...)


should i give these a go? thanks for any help!


also, i've been reading that i should buy some 16 gauge speaker wire and a better subwoofer wire with this particular set... can someone point me in the right direction on where i can get this stuff for a good price? online or instore suggestions would be great! thanks!!!
