I have a annoying winning noise thru the speakers, most noticeable between 50-60 mph goes away with letting off accelerator . Everything in the truck is factory nothing extra. I have the factory upgraded alpine stereo. Checked alternator its grounded and putting out correct amperage. This whining is beyond annoying and I can't seem to locate the source. I have some in-line noise suppressor but haven't installed them yet figured I'd check here first...
