Hi, I just got a LED TV and I don't like the audio quality (it vibrates during low frequency sounds). I want to buy some PC speakers to use them on the TV and for playing PS3 too, mainly because Home Theaters are expensive. How I plan to connect them is just with an RCA (2males) to 3.5mm(female), which means, directly to the TV (no amplifier or the such, just the subwoofer that comes with the speakers). My questions are... will that give decent sound? And could I hear the PS3 too since it is connected with HDMI? Help will be highly appreciated, I'm not very good with audio-video setting ups.
