Is this "noise reduction silencer" worth getting?
 

I've got a little bit of audible alternator interference. Would it be worth it to install this Monster Calbe product?

I know some here will disagree with me here, but I think you're better off
 

identifying the source of the noise (e.g. bad ground, proximity of power/signal, etc.) than this sort of bad-aid solution.

Of course, if all else fails go for it.

Hi,

You don't need this...
Take the time and find different grounds mounts for your amp and deck, this is whats causing your audible alternator interference.

Try it out first.
