dnx7140

Hi- I am pulling together an audio system for an 06' Ford F-250 CrewCab with electric rear window. So far I have an Kenwood DNX7140 HU and 4 BO SL80 door speakers. I intend to purchase a subwoofer and an amplifier. Is the ProBox with single 10" sub a good choice for bass? What amp(s) do...
