Speakers make loud screeching/whining noise, only when car is running?

[QUOTE="juanmgarza26, post: 8291588, member: 645753"] Sounds like bad grounding. I Dont know what kind of frame your vehicle has but if it had a chassis ground there. Disconnect rcas from amplifiers and see if the noise still persists. If it does you have bad grounding. If noise goes away when you disconnect RCA's, track back RCA's and run them about 12" away the positive runs that power your amps. [/QUOTE]
