How can I stop my HU's metal cage from vibrating ?

[paco]

Hi,

I have been using an Alpine CDA-9831 head unit for about a year in my Cooper, but the surrounding metal cage (the one you have to slide the head unit into) rattles a lot with motor and road vibration.
Is there a way to stop those vibrations ? It's driving me crazy!!


Thanks,

Some pieces of felt or velcro

Or take it out and reinstall it more tightly as it shouldn't be doing this. I know this is a ball ache but it should resolve the situation.

Mike,

Thanks for the tip! Is this a known problem with Alpine's metal cages or a "standard feature" with most head units ?

Where do you position the velcro for optimal vibration attenuation ?


Thanks!

Charlied,

When I originally installed the head unit the metal cage's fins seemed to vibrate even before sliding the head unit into it. The head unit seemed to be very tight with all the fins/clips of the metal cage, do you think it is an installation problem ?


Thanks,

my alpine has some very thin fins on the cage that "ping" into place when its fitted...they creak and ping if i lean against the downtubes hard...think i need some felt in there.

bimini,

Would you put the felt tape on the fins themselves ?

I know this is an old thread but I have issues with the cages on aftermarket heads too. Ever after pressing out the metals pins as much as possible the cage is still loose.

Any one know of brakets you can get that replace the slide in lock mechanism and allow you to use the screw holes like the oem head unit does? This would make it a lot hard to nick the head unit, right now a few good pulls would have it out!

This is indeed an old thread I have sold my head unit since but have never got around to silencing the annoying metal cage vibration!
