Thank you for the info. I have 1 thing to ask. I assume that Hertz Energy is the mind range product while Hertz Mille is the high end product. For a beginner like me, should I start with mid range product or straight away start with the high end product?

Thank you again.

Hertz have been in the Circuit for some time now BUT their lower range models do have fakes in the market. Not as rampant as before tho'. As long as you get em from a reputable dealer with the local distributors seals and warranty - it should be aight.

German Maestro are the new boys in town. Ann offshoot from MB Quart. Pretty reputable. Have heard good things about em'.

The basics of an upgrade from Stock is always either the Speakers or Headunit - depending on your budget.

Most modern Stock headunit caters "adequately" for aftermarket speakers, SO, my suggestion will be to get a good set of speakers - components if possible.   

Depending on your budget (RM600 - RM1000) will be an healthy range for a decent midrange component sets. Go for Brands that specializes on Car Audio i.e. German Maestro, Focal, Morel etc.
