hey all,
i recently changed my head unit over on the o2 punto, but there are a few wires that i didnt have conectors on the head unit for. Do you think i need a wireing harness of sum kind to connect it all together. The cd player works fine and so does the fiat branded sub just that there is no bass sound coming from the frount of the car however it did before, think the cables must be for a speaker in the front of the car in the dash somewere. They are only small connectors with two wires coming from them and i think one of the connectors is orange.

Thanks
Tommy
