Johnny Woo (August 10, 2001): Manufacturer of car amps and speakers based in Singapore, their products were usually sold under the ADX brand but the company also was a large OEM for companies/brands like Hifonics. ADT designed their own loudspeakers but their amplifiers were designed by Zed Audio. Appears to have started up in the early 90's and active at the least into late 2001.
