I've had my evo for about 10 months now, and ever since I've had it there been this really irritating rattle coming from the front left side of the car, any time I have the radio on. Stripped the door and checked all the fastenings and I even replaced the speakers but the noise is still there :bang: When I took it to the dealership, they said theres nothing wrong (what did I really expect?) but the sound is STILL there! Anyone have any clues as to what this might be please?
