A Blaupunkt PA2100 2-channel amplifier I got as a Christmas present last year just quit on me. No sound is coming from my pair of Infinity 6x9's and the power light on the amp is blinking. I know the speakers work, the voltages are steady, and a good current is running through the remote link that turns the amp on. If it's something simple, please tell me. I would save me some money because I don't know if my parents filled out the warranty card. If not I could get that JBL 2-channel amp I was looking at. I would like to save this amp if I can. Please give me some suggestions.
