Trying to make sure I understand you. So currently, you're running your speakers off your Sony head unit, non amp, but you're trying to run the speakers out rca to eq then from eq you amp and from amp to speakers? I'm guessing you already have the amp on wire ran? Where is the equipment located? If in the trunk, do you just have wires run from the trunk to the head unit? Where are you tying in for the speakers (location and wire color)?
