Hello. Quick question. I. Have loud alternator whine only when I turn my hu off. After the hu is turned off,there is a 6 second delay, a pop,and then the constant whine with the idle. When I turn the hu on there is an immediate pop,and then the noise is totally gone.The pop is most likely the amp turning off and on,although it is supposed to have a feature that prevents that.Rcas are ran away from power wires. Everything else seems good. This is really the last thing I wanted to deal with. Car is 2000 deville. Hu is kenwood x995. Components jbl c608 gti mkii. Amp is soundstream ref2.640. Sub not installed til I get this solved. Any help will be appreciated.
