This is caused by many possible problems, but the common ones are: ground issues, bad RCA cables, poor ground on head unit, bad speaker wires, speaker wires touching ground, problems in the car's electrical system, bad spark plug wires, bad ignition coil, cracked distributor cap, bad engine ground strap or battery ground cable, corrosion in your ground connections, poorly shielded amplifier (ie a cheap one), EMI or RFI induction into the speakers due to speaker placement, and mismatched pre-amp voltages such as a head unit that produces 4 volts feeding an amp that can only handle 2 volts. You have one of the hardest problems to nail down, byt be methodical and only try one thing at a time until you find it. Good luck.
