What Pwr sup. would work to power a 3000w indoor/outdoor system? I plan on running 8-8ohm 15"subs wired down to 2ohm per 4 subs, 16-8ohm 6 1/2" wired at 2ohm per 4, and 4 professional stage horn tweets. Everything will be installed in four yard friendly (rolls on grass) towers. Gonna have a yard full of lovely BASS... Probably use it for an outdoor theater system for summer and fall..
