I have recently installed a Boss c-650 4-channel amp to infinity 52.5, 5 1/4 compenents and also infinity 575.5 5x7's. I also have a 1 farad capacitor running to it. For some reason when the car is off, they sound great, but when it runs I get a high whining sound out of the tweeters(both the component tweeters and the ones in the 5x7's). The noise increases when I accelerate. I have two fuses running from my amp to try and dampen the power, but that has failed. I also tried to reground it, that failed also. I need some help! Does anyone have a solution to my problem? Too much juice from my alternator???? Please help!
