Ok I'm not to good with audio work but I've seen it done countless times by a friend LoL but he always didn't keep it for a odd reason just kept buying the stuff hooking it up playing it for a month or 2 and then selling it XD. SO since my speakers are 800w and 4ohms would I need a amp that can do 4ohms and how much wattage should it be? and If you didn't see my post above I seen some tuts for hooking a PC power supply to power the amp just needs a high amperage so I just need to find a amp that will power these. My friend also said that these speakers didnt work but he most likely in my mind didn't hook them up to receive 4ohms and from what he said it just bumped them a little bit plus the speakers dont smell burn or anything
