Answer 1

Is there still a factory headunit? Your headunit, whatever it may be, or amp, could be going bad. Also check all speaker connections. sometimes, at the back of the speaker, the (+) wire or terminal could touch metal and that could be shorting out your speakers as well. Just remove all speakers and individually hook them up. Keep your radio on while you hood them up and be sure that none of the speaker wires in the car is touching themselves or the metal in the door. This is common as well.
