Double Bass Not getting enough VOLUME from my amp!

@Riley Z .. check your pick up, put the Carvin in bridge mode and feed that 410 the 900 watts.. the cab will handle it perfectly fine, unless you some out everything. Refer to your owners manual for directions on this, or call Carvin and someone Should be able to walk you through it.. Should be plenty of volume.
Breath, relax, have fun, and
Good luck!
