your red is going to be the power and black the ground. the other wires are going to be you speaker inputs your going to have a hard time to get the to work in your car b/c you dont have any rca's to run the signal to the amp. this means your going to splice one of you rear speaker's with the amp to give it signal. the problem with this is your going to get your highs and mids throught the sub (you want just the lows 80hz and below), which means it is going to be crazy distorted. unless you just ditch the factory amp buy an after market one and just use the sub. any further questions pm me.
