if can afford branded go buy branded......but let me tell u, the stuff u must be using, pre, speakers,etc must be chinese........and even the companies like alpine, rockford fosgate , jbl, mtx.etc etc, are chinese though, so wouldnt buy them also, chinese amps are gud , the company vtrek isn't a newbie in this field, from severa years it was making the stuff for the company jvc, so later they started their production by name of vtrek........
if u want a branded amp, a guy here on pw is selling kenwood 8104d, its a gud amp , gves 500rms at 2ohm, enough to run a d4 at max and is mono to........
