If a RetroSound radio cuts out or freezes when the engine is running or while driving, this could be due to various problems:
1. Sound dropouts: Short circuit in the loudspeaker cable. If the speaker cables come into contact with each other or with the body, the radio's power amplifier switches to "Protect" and there is no longer any sound. This also happens if the speaker touches with one of its connection terminals the body. Then you have a typical loose contact problem because the vehicle moves and the terminal sometimes touches the metal and sometimes not!
2. Sound skips or freezes caused by the alternator: If the alternator sends voltage spikes into the electrical system, the radio can either freeze or temporarily not emit any sound. Such voltage peaks cannot be measured with a multimeter! It Can only be measured with an oscilloscope. To find out whether the problem is with the alternator or the ignition system, you can leave the radio installed in the vehicle, but the power supply must be completely disconnected from the vehicle. For example, via a 12V power supply or a battery that is not connected to the car. The antenna should also not be connected to the car.
If the error continues, the ignition system will be the problem. If the error is gone, a voltage stabilizer can help. Some customers have already had good experiences with this product: EU012DCAC408. It takes voltages from 8-40 volts and outputs a clean 12.5V with 10A for the radio.
3. Sound skips or freezes caused by the ignition system: If the problem comes from the ignition system, suppressed spark plugs or plug connectors often help. We've also encountered a hairline crack in the distributor cap! Modern high-performance ignition systems, such as those often retrofitted into US classics or sports cars, can also cause problems.
