Hello
You will want to connect the wires at the amp as they shold be. At the speaker end you NEED to connect all 4 wires as they should be + and + to + post and - and - to the - post (unless using phase reversing then keep togother ++ and --and reverse). If you do not you MUST TAPE off the lose wires as they connect as a single + and single - wire at the amp which means that if not connect at the speaker as well you have two hot wire floating around there that can short out. Also by connecting the 4 wires you are just increasing you wire size, which in almost all cases is a good thing. Good luck Bob
