I tried to install an after market double din radio in my 1993 Ls 400. The wiring to install this radio has got me stumped. I have a Nakamichi audio system with a separate Nak amp.. It doesn't matter to me, either bypass the Amp or use it. I upgraded the speakers already. I had the radio hooked up and thought everything was correct, then the radio started smoking. The radio is now disconnected, until I can get some good advice, but now the air-conditioning stopped working completely, nothing. I checked the fuses, the dome light fuse was replaced, but still no air. Does anyone have any advice on what I should do next, I would really appreciate it. I live in Hattiesburg Mississippi and it's Summer the heat and humidity is unbearable. Help.
