I'd say that it is the reason why you are experiencing the randomness with the bass. You are in effect creating a situation where the wires do not make contact with the terminals, or are either causing a extremely high resistance due to an improperly connected terminal, therefore the sudden increase and decrease. And I would also caution about your gain settings, as if you are trying to compensate for the lack of bass from the inadequate connections, you are likely to send the amp into protection mode or worst case scenerio, a meltdown.
