Sajme, did you ever get the stock amp to work? I just started a project where I would like to use the stock amp in my 99 GS300 and I am running into the same issue. I can't get the amp to turn on and the only missing link seems to be the BUS+ and BUS-. Does anyone know if I can just send voltage down those wires to get the amp to turn on? Thanks!

I am installing a carpuer in a '99 GS 300 and need help infiguring out how to signal the factory amp to turn on. The amp is on the passenger side behind the glove box. I have searched thr forums and have found a couple different wiring diagrams, but not seem to do the trick. I can figure out the speakers once I get the amp to turn on. Does anyone know or have any suggestions? Thanks!
