Just installed a Bluetooth amp to my car, to clean the dashboard with a blank faceplate, I ran a cable direct to my battery but I am getting the amp to shut down protecting maybe because of an overload since it doesn’t get energy from the regulated board I think. Can anyone confirm if my assumption is correct or if my regulator is not regulating correctly.
Thanks. I updated the photo. And my wires |

Here's some more wood to throw on the fire.
If your voltage regulator checks out & your grounds are kosher, as previously discussed, I would again suggest that the amplifier is bad. If there is alternator noise while driving, then I would also suggest that the amp's internal PI filter is bad & leaking to ground (assuming it has one) due to a bad capacitor. External PI filters were used in the old days to eliminate alternator noise. They consist of an inductor in series with the hot input along with two capacitors on either side of the inductor which run from the hot input to ground. An intermittent leaking capacitor will short to ground & perhaps blow a fuse depending upon how bad the short is. I've run into this problem before with OLD audio gear. Again, just some more potential BS to add to this discussion. Your wiring looks very clean. Are your loudspeakers hooked up independently or in parallel? Series would be a no no from a sound quality perspective, but this will decrease the load. The lower the total resistance, as in the case of a parallel connection, the larger the load. I suppose this is a moot point since the system works fine when the car isn't running. Ergo you have a defective amp. They don't test these things prior to shipping. I would return it for a new one. Can you contact Blaupunkt for additional support? Does the thing come with a schematic? Finally, what happens when you disconnect the speakers? Can you see if the amp shuts down while hitting the gas pedal? Finally again, this is a Class D amplifier. They are prone to power supply issues. From the internet: "Power-Related Problems: Power issues are another common concern. These can range from the amplifier failing to turn on to problems with maintaining consistent power output during use. Causes can include faulty power supplies, inadequate power sources, or internal component failures, such as issues with the power management circuitry." https://brzhifi.com/blogs/news/solving-comm...troubleshooting Hmmm... Is the amp getting hot & going into thermal overload & subsequent shut down? Call me at 408-802-0155 if you wish to discuss this in greater detail. Leave a message if I don't answer.
