    Hey Ronald_93, may not be able to answer your question, but you may need to provide a little more info such as the following: 1. Make, model of amp 2. Does your factory radio have RCA/Line level outputs (if not how is the amp connected into the system). 3. Where do the speaker wires terminate/connect? Are the speakers connected to both the amp and the car's radio at the same time? 4. Can you clarify what you mean by "go in and out". Is the sound cutting out and coming back on?

    Sure somebody will be along to assist if I'm not able.
