Question about 2009 Ford Focus
I am trying to hook up an amp to my stock cd player, and I need the wiring diagram and how would i do that?
Without preamp outputs,you need to get a speaker line matching transformer.it takes the speaker signal,reduces the level,puts it thru a low pass filter if it is for a subwoofer. it basically is a tranformer resistor network that drives a set of rca plugs that will go into the amp. the only tricky part is noise,speaker lines have a poor signal noise ratio if you amplify them.
