My stereo only has 2 inputs for the rca's a front and rear. Where do the rca cables from the harness and amp go? Do i plug the amp rca's into the rear and harness rca's to the front? They both sound better plugged into the rear, is there a way of putting them both in the rear, ive heard somethinga bout y cables but dont know how to use them.

 

sorry to split hairs but your post confuses me. Your deck has rca inputs? I will assume you mean outputs since you are talking about an amp.

I really need a list of the equipment that is in the car to help as I am not sure where you are going.
