I have searched this site and emailed toyota trying to find out some info with no luck. I would like to know if anyone knows how many watts the factory amp in a 1993 80 pushes to the front doors, back doors, and rear "sub"(i read that the sub was around 15, but that is the only one anyone has spoken of). I am in the process of reconfiguring my speakers and this info would be a great help. Thanks, Scott
