One of my doors also rattled thanks to the lousy stereo installers at Pasadena Auto Sound. The crossover unit was just dangling inside the door.

 

ok I guess I am a totally n00b but what is a crossover unit? Also is it near the speaker?

 

bump

 

A crossover separates the highs from the lows and sends the proper frequencies to the speakers and tweeters.

 

hi all,

I just added to the old thread and hadn't seen this new one about the 6K plus vibration/rattle/noise on passenger side ....

here's what i posted there...

I found the source my vibration/noise at 6000+ RPM's !!!!

For me it seems that the passenger side door sill - was the cause... thus the sound as if it were coming from inside the door itself... the sill is held in place by three white clips... my sill had only 2 of the three clips - I re positioned the two clips from front 2 spaces to rear 2 spaces and voila!!! went out and hit VTEC in assorted gears and the noise above 6200RPM is gone! I will also put a piece of velcro?one side under the plastic sill so as to absorb any remaining vibration down the road
