Unfortunately after I had installed my subwoofer two weekends ago, if I hook up my front infinities I get horrible alternator whine. I have tried multiple new grounds for the Rockford amp, but nothing seems to help. Right now I am just running my back speakers and these boxes that I made for some 6x9 Pioneers that sit on my backseat floor as well as my sub.
