I recently put new front door and rear door speakers and kept original wiring harness and factory tweeters, also a news deck but i am still concerned about the factory wiring. I would like to run all new wires is the crossover built in to the factory tweeters or am am i looking for such a thing in the kick panels
Thanks any input helpful

 

the crossover is actually the poor mans version: a capacitor wired across the terminals of the tweeter.
And the factory wiring is actually not bad, I wouldnt worry unless you run more than 100w per door.
