I am looking to see if anyone here can test and fix an amp (if needed) for a reasonable price. I want to make sure its in proper working order before i sell it. The amp is an Infinity beta digital 300. Ive noticed that the red protect LED stays lit even when the car is off and sometimes the amp will go into protect mode while listening to music...i dont rememeber it doing that before. Either reply in here or send a PM. Thanks
