i am DEFINATELY not getting the volume out of my b4r that i should be. My 120 watt 12 in hartke kickback is blowing the doors off my ampeg volume wise and i dont knwo whats up. I have my b4r bridged to an ameg 6x10. I had the gain and volume a bit past halfway and i could barely be heard over a couple of guitar 2x10's with their volume 1/3 of the way up. I pused in the mono switch. Is there anything else i could be missing. Help me out guys.
