Hi I would like to know how you would set up 2 Peavey Pr 12 12" will handle 400 watts program & 800 watts peak @ 8ohms, can do 4 ohms also, To a Crown XLS1500 power amp, to get the best clean sound? I just got the XLS1500 power amp and would also like some tips also. just doing a mid show for DJ but more power mean cleaner sound I think. Should I turn the amp all the way up? also got this mixer Behringer XENYX X2442USB USB Mixer with Effects, to go with it. Tell me what you would do to setup all this for karaoke and stuff thanks.
