Car radio installer with GOOD English?

[trevoromgh]

Hi everyone .... Just had a new radio installed in BKK but fitter looked clueless when I tried to explain there is now a whine from the speakers and said he couldn't fix it and that the radio I purchased was cheap (which it was but that is besides the point).  From checking the internet the likely problem is down to either a) a bad earth/ground connection  or  b) interference from the alternator which needs a 'noise filter' fitted to the power lead.

 

Does anyone know of a car radio installer in CM who can speak GOOD English who might understand when I explain the above please?  Would use my wife to translate the message but she too does not understand what I'm trying to say as it's too technical.  Arrrgh!

Managed to find a place in BKK eventually.  Took them 30 mins to fit a noise filter and cure problem.
