Well today I tried to turn on my sub which I do with a switch that turns my amp on and after about 5 seconds, which it usually takes to turn on, I did not hear the sub come on, so I tried a few more times and even turned the cd player in the car off. (dont know if that does anything) When I opened my trunk the thermal red light was blinking....not a constant blink but a blink about once every 10 seconds. Someone told me this could be because of the AMP overheating, but I left my car off overnight and about 8 hours later after trying to turn the sub on again, I had no luck, and the AMP is still blinking the thermal light. I am wondering what to do next? I will mostl likely take it to the place I had the amp and sub installed at on Monday and see if they know what the problem may be, but any suggestions would be great. Thanks in advance.
