Question about Kenwood KAC-9152D Car Audio Amplifier
I connected all the wiring and when i turn the car on, the red light stays on for a second and then fades off but the fan continues to stay on. There is no audio output to the sub other than a quick popping noise when the light turns on. i checked the voltage and everything checks out fine. i am transferring the system to my new car and it worked fine in my old car. I have tried connecting the power control wire straight to the battery to see if my unit wasn't giving off enough power to keep the amp on, i got the same result.
Try using a better ground. while new cars are great, they also have more paint and plastic in the works...so finding a good ground for your amp to run off of isnt always easy. you can try running a gbround cable straight to the negative terminal of your battery to test the amp, poor grounding is the most comon cause of amp failure. ps,the fan may be staying on as a protective service, as if your amp loses ground whenpowered up it will keep the cicuit boardfrom heating up on voltage surges.
