I scan the business card that the taukeh gave to me and put it below. The name of the taukeh is John, the name of the shop is Park City Car Audio Acc, and the location is actually in Telok Panglima Garang (Klang-Banting)


I don't know how to differentiate between genuine and imitation products, so I ask the taukeh about it. The taukeh said every Hertz packaging box and speaker has serial number. The serial number on the speaker should be the same as the serial number on the packaging box. I can email to Hertz headquarter to ask whether the serial number is valid or not. The taukeh said he also have the stock of imitation Sony Xplode at his shop, but he said he will never put the brand 'Sony' whenever he sells imitation products. He said nowadays it is easier for the government to trace what he sells through GST invoice, so he will never put the brand of the imitation products in the receipt. Otherwise, it will be easier for customer and government to take action against him.

I tried to google the name of the shop and so far I found many people tagged their location whenever they visit their shop, which is shown below:
Park City Car Audio Acc

I even find a post from Vozaudio (the authorised Hertz and German Maestro dispributor in Malaysia, according to Hertz and German Maestro International website) showing that they send their Hertz demo car to Park City Car Audio Acc, as shown below. Based on this, I assume that Park City Car Audio Acc gets their Hertz (and German Maestro) stocks from Vozaudio and those stocks are genuine.
Vozaudio Sent Demo Car to Park City Car Audio Acc

The taukeh also told me that Park City Car Audio Acc is the only authorised seller for Hertz and German Maestro in Telok Panglima Garang.

However, I'm not sure whether workmanship at Park City Car Audio Acc is good or not.
The taukeh adviced me to start replacing the speakers first. If I am satisfied, he said I can come again to upgrade the Head Unit.

So far his shop still sells Hertz at last year's price. Maybe because they still keep the stocks that they bought before the price went up. I go to his shop again today and he quoted me this price:
1) Hertz Hi-Energy HSK 165 Two way component, RM1800++
Hertz Hi-Energy HSK 165 Two way component
2) Hertz Energy ESK 165.5 Two way component, RM800++
Hertz Energy ESK 165.5 Two way component
3) Hertz Dieci DCX 690.3 Three way coaxial, RM580
Hertz Dieci DCX 690.3 Three way coaxial
4) German Maestro Concept CS6508 Two way component, RM900++
4) German Maestro Concept CS6508 Two way component

The taukeh also said that both Hertz and German Maestro perform almost the same for the same price range. The only obvious difference is in terms of appearance, Hertz looks more awesome while German Maestro looks plain
Since I am the beginner, the taukeh advised me not to waste money buying expensive high end products. He advised me to start with the second and third Hertz products above for front and rear speakers (or any equivalent product from German Maestro). He also told me that even a Mercedes owner bought only the second Hertz product above from his shop and was satisfied with the performance (without buying high end product). He said if I purchased the 2nd and 3rd products at the same time, he will qoute me RM1400 flat.

I think he has. But you may call him using the phone number in the business card that I scanned to double-check. Don't forget to inform me what he said :-)
