Box specs and detail of your electrical would be a pretty decent start to figuring out your problem seeing as that is usually where the culprit lies. However, you also need to define what you mean by that "big boom" as that is different for everyone. More than likely, you're either not actually giving your subs 3 kW (doubtful you would be even if you had proper electrical due to rise) and/or your box isn't quite what your subs want.

might want to have this moved to the subwoofer section, this is for music topics. But on topic, your question is about as vague as it can get. You need to give a t lot more details.
