I want to convert my Ampeg BA 115 combo bass amp into just a cabinet and drive it with a slightly beefier power amp than the packaged 100 watt amp. The 100 watts isn't powerful enough for my monitoring needs and my goal is to reach a maximum of 250 watts. Since I am making this power jump, I am going to replace the 15" speaker to accomodate the extra wattage and my question is: Do tweeters blow easily? Should I upgrade the tweeter along with the 15" driver? Thanks for the input.
