ok i have been running my sub and amp setup for a good 8 months or so and it has never given me any problems. Until now for some reason my amp isnt getting enough power any more to run and it shuts off. My car still starts fine and i have no problems running with out the stereo. So my question is do you think this is my battery or my altinator or something that i have absolutly no idea about lol thanks any help is appreciated. ---

How do you know it doesn’t have enough power, did you check the voltage? ---
