Hello out there, I have a GK neo 4x10 cabinet (800w 8 Ohm) powered by a Hartke 500w 8 Ohm amp. Question: Can I add a GK neo 1x15 cabinet (400w 8 Ohm) to my set up? Will the Hartke 500 have enough juice to power both cabs? How will the 1x15 affect the sound? I never intended on adding an additional can but found a used GK neo 1x15 for $250. Is this a decent price for the cab? As always, thanks a ton for your input.
