if i get the carvin rl1018, then i have an 18" cab and the 4x10 cab. i certainly dont need all that power (yet). could i leave one cab at practice space A and leave the other cab at practice space B and just move the head? would this be a good idea? also if anyone knows about this amp could they explain to me how much watts i could play at through each separate, and together? im still confused about all that ohms and channels and stuff thanks you!
