+1 to zennn's opinion..

these amplifiers might not be as reliable as the reputable ones..

lets say these amplifiers might cost you rm300. burnt after 6 months. then you would need to buy another amplifier, lets say another cap ayam at rm300.

why not save up rm600 to buy a second hand reputable amplifier that would last for more than a year?

maybe i can put another 2cents in here.. hehe.. in my opinion, i believe that getting a 4channel amplifier for speakers is good. even if you only use a set of front component and 6x9.. you can forget about the 6x9... can reserve the 4channel amplifier for front active setup in future if you feel wanna go active.. then you wont need to buy another amplifier.. its kinda saving money too.. hehe..
