fyi, these distributor are based on KL and shah alam as i get their address.energie said:Golden Auto, Acoustic Edge, Narchin & Rock are all dealers for Pro Ice, NTC,Extreme Audio & Trio Auto. They deal with authentic JL Audio, Kicker, Coustic, MTX, JBL, Infinity, Impact Audio, Polk Audio, Phoenix Gold products among many others. Dunno about other installers, but like I said, these guys are top draw in Penang, so I wouldn't think they'll risk their reputation with counterfeit products.
