i'm about to installed new door speakers in my truck and saw how little the wires are at the factory plug. are the factory wires good enough for some nice 6*9 with 3 ways? or should try to run new speaker wire all the way to the nav unit?

thanks
mike

 

Factory wiring will be jst fine.

 

factory wires usaully are a little smaller but as long as you not hookin up a bad *** amp to your speakers, they are more than capable of handling the load
