hi all ive been searching all over trying to get some answers and opinions on this. i cant seem to find a definative- for sure no question about it- answer. i have a GK 800RB on the way and will purchase some cabs. i know most people run this amp full range. i also know the top amp is 100w and only 8ohm,while the bottom has two inputs and can use 4ohm. i found this question but no definate answer i could see....some say yes and some say maybe. can i for sure use a 2x10 8ohm on top and a 4x10 4ohm on bottom running full range? i plan to get avatar cabs.(based on price for my budget) thanks in advance for your help!
