need more facts about the amp. Amps that are ACTUALLY that powerful are rare and very expensive, but the cheaper brands can print whatever number they want to try to get them sold. 3500 watts max or rms? What's the fuse size? If it IS 3500w do you have the electrical system to provide that much current? At what impedance does it produce optimal power? A model number would help. Also - you said the sub is dvc - is that dual 2, dual 4???
