So I just picked up another 6 bass shakers, for a grand total of 8 Aura bass shaker pros. There will be 4 in each couch. Trouble is, I know Ohms law about as well as rocket science. ;-) I can either get a 1-200 watt PE plate amp and use that in mono; or I have an older QSC pro amp that I can use in mono or stereo. So how do I determine how large of an amp I need, and what load to present it with? I've read through the archives, but never figured out HOW to do it. Thanks in advance for any advice! FWIW, parts express is out of them; and only 1 guy on ebay has any left. If you want 'em, better jump on them right now!
