new speaker vibrates sounds blown

I look all over the forums and could not find an answer. I have a 2001 GMC Jimmy 2dr with a stock delco Am/Fm Cd player. I went out and bought some Jensen 6.5 coaxils for the doors and 6x9 triaxils for the rear panels, because I had one 6x9 right side not working and one door speaker (right side) was starting to make noise. When wiring the speakers I used the wiring color codes from this site and the manufactures instructions to the letter. Now when I finished and turned on the system all 4 speakers work but I am getting a Vibrating noise out of the right rear 6x9 speaker only (at normal volume), Bass and treble are equaled between left and right sides, so are the fade and balance. It gets worse the louder you go and is not as bad in lower volume ( it sounds blown to me). I disconnected each speaker and ried the radio to see if any others were doing it as well and they were all good, it is just that right rear 6x9 speaker. Anyone have any Ideas before I take my truck all apart and remove the speakers to return them. THANKS!!Big Casino

is it possible that the rattling noise is due to poor installation???

It doesn't rattle, it  is a vibration like there is to much bass, but the bass is not to high and it only happens in the one speaker. All others are ok..

Could the problem be from going from a 10 Ohmn speaker to a 4 Ohmn speaker? will swap out speaker tonight to make sure it is the speaker. hope it is not the head unit, but if it is does anyone have a good suggestion for a replacement?Big Casino

Stock was 10 ohm, and you replaced it with 4 ohm? Theres your first problem, sounds like you have the Bose option? If thats the case you need to replace with the same crappy blows speakers, or get a new headunit and run new wires directly to the aftermarket speakers. Those speakers are absolutly junk, you got what you paid for, most likely a blown speaker, I have seen that many times, people would bring me crap they bought from wal mart and they were blown right out of the box. Seriously, save your ears from the horrible pain those speakers will produce and return them, $20-$50 more at a stereo shop and you will get MUCH better speakers, if you plan to get a new head unit, but if not, then you need to find 10 ohm speakers or you will fry your factory head unit/amp.2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.
