Any suggestions? My friend wants a system that (and I quote), "CAN BLOW MY FACE OFF!". Hopefully not literally. So, just wondering what he should be looking into. He likes my setup, which is an 800 watt Samsung surround sound/5 DVD player combo. I'm thinking he wants something with lots of speakers, a really good subwoofer capable of some awesomely heavy bass, its needs to be really tough (hes not gentle with things), and it needs to have a hookup for MP3 player's (which is probably a standalone cable that hooks up through A/V, but an included line would be nice). Any suggestions? His price range is no more then around 600 Canadian dollars. Any help is appreciated.
