Speaker amp construction Answered

i've got a 30W ELK-1RT speaker...it's designed for use with alarm systems etc...nothing really fancy....but we're attempting to find a way to plug it into a computer out in the factory i work at...we're having a rediculous time finding prebuilt amps to drive this thing from a PC line out port....wonder if anyone has something prebuilt or schematics and parts needed to power this speaker from a PC


"a real 30W is LOUD." hehe that's what we need....out on the floor of a manufacturing facility with people wearing earplugs...we need loud
