buzzing noise from front speakers

i just installed new alpine sps460A speakers in my 97 cavy. i did it myself because i didnt want to sacrifice my pride and i wanted to learn my car. i took out the old speakers because the sound quality was bad in the factory on the drivers side but when i removed the factory the speaker cone was not damaged. i put in the alpines and when not in the door they sound perfect and are amazing but when they are attacted to the door they make a buzzing noise that is worse than before. its bad on the driver side when idling and only gets worse with driving. when idling the passenger is fine but also makes the noise when driving (i listen to a lot of bass). i took off the door panel probably about 4 times on the driver side yesterday because every time i thought it sounded good it would make the noise again. i checked all the screw connections and everything and even tryed different combinations of tightness on each screw and even when theyre on there tight it still makes the noise. im thinking it might be another piece somewhere in the door that is loose. any idea what it is?

im going out again to investigate today and put in the back speakers. ill update if i figure it out.

never mind i solved the problem. the speaker kit came with a plastic ring to put between the actual speaker and the metal mounting piece. this ring had no way of being attached and i feel stupid now for not seeing that in the first place but nothing rattles now so i win.
