    if you disconnect the sub, will it still make that sound?

    you may have alternator whine also

If i disconnect the sub and dont hear it what does that mean or if i do hear it what does that mean..Today i ran new rca wires and put in a new headunit but i still get it

    make sure the ground on the amp is grounded good, check the ground on your battery, where it grounds to the body/frame. take the grounds off and scrape the paint off where the ground wire contacts the body/frame = problem solved!!!, done this on at least 5 friends cars, works every time... if not just pm me
