2001 Boxster S stock radio problem


Recommended Posts

Hey guys, I really need your help.

 

I have a 2001 Boxster S with a stock radio head unit (with cd) and stock amp. Recently have been getting periodic crackling noises (sort of like a scratched vinyl record) from both the radio and the cd, and the warmer the outside temp, the worse it gets. I sent the hu into Becker Autosound but they couldn't duplicate the problem even at high temp.  I next bought/installed used HAES 4X40 amp which corrected the problem for a short time but now its doing it again with the replacement amp.

 

Any suggestions as to what might be going on would be greatly appreciated. Thank you in advance for your help.

Try installing a ground loop insulator. 

 

It sounds like you’re suffering from a classic ground loop problem. Ground loops occur whenever two components are grounded in different locations that have different ground potentials. The right way to fix the problem is to make sure that everything is grounded in the same place (or at least that every ground has the same potential). The easy way to fix the problem is to use an in-line noise filter.

 

The right way to fix the problem is to trace down your sound system wiring and attach the grounds from components like your head unit and amp directly to the chassis in the same place. Usually under the instrumental cluster.

 

Ground loop isolators basically consist of an input, an output, and a transformer. The audio signal enters the isolator through the input jack, passes through the transformer, and exits through the output plug. Since there is no direct electrical connection between the input and output, the ground loop (and any interference it generates) is effectively “isolated” from the signal.

 

Here is a ground loop isolator noise filter available on Amazon for $8.00 plus shipping or free next day if you have Amazon Prime.
