Sometimes, the electrical charges caused by the engine get picked up by the wires, which creates undesirable noise known as ‘ground noise.' This problem occurs if the negative part of the cable is not securely connected to the body of the vehicle. we can fix it by ground loop isolators. or the RCA cables are faulty, they pick up engine noise or a whining noise from speakers when accelerating. I had a unit from XTRONS a few years ago, it did has the noise problem with the speakers, I fixed it with ground loop isolators. Actually this doesn't happen to XTRONS units only, most of the aftermarket radios have the same issue even Alpine or Pioneer. It is easy to get this adapter cable from any car accessories shop. Installation is simple. You just insert the coaxial plug into the stereo socket of your stereo and connect the RCA cables to your speakers to the stereo socket on the unit.
