Hey guys, I have 4 large speakers that I'd like to drive. they are large box speakers contiaining a large driver (2 are 15's, 2 are 12's) a midrange speaker, and a small tweeter. I want good clarity, I want it loud, and I want to be able to drive it constantly loud (no overheating, frying circuits, etc) No regard for my hearing. I had a 300w amplifier that came with the stereo, but somehow it got fried (it's 20 years old, so not really surprised) and I thnk it was only originally designed to drive 2 of the speakers (though it had connections for 4) I'm having a hard time finding a 120 v amplifier with the kind of power I want to produce. My experience is primarily car audio, so my mind went initially to this... then in order to give this thing enough clean 12v power, I was thinking of a high end computer power supply like this.. http://www.microcenter.com/single_product_results.phtml?product_id=0290512 build a box, throw in some computer cooling fans for good measure. anyone see any pitfalls I might run into with this? anyone know of any good quality 120v amplifiers or recievers with 500 - 1000 watt 4 channel outputs?
