I own an Ampeg BA-115 and I was wondering how I could get more power out of it without buying a completely new amp. I list the problems with this below. Not only does it not have an external speaker output, this is what it does have: a line out headphones jack CD input and a passive and active bass inputs. is there any way to connect another speaker to it? it looses some of its tone when I turn it up more than half ways i loose a lot of tone...is there anyway that i could make it so i don't loose as much tone or so that i don't have to push the speaker so hard? and by the way it is a 1x15 combo.
