I just chopped up my stereo wires and failed at installing an amplifier. My amp will not turn on and worst of all I do not have any sounds. I tapped into the wires leading from the factory amp to the speakers. I connected it to speaker level inputs of a 4 channel amp. I already bought component speakers and put the new tweeter in the midrange spot up front. Then I connected the speaker output of the amp to factory speaker wires. I connected the remote power and tapped into the factory remote power(white wire). All the power connections are good.
