Mine are all just bare wired.
With the crossovers, you will have the wires coming from the amp going into the input side. Then the woofer wires go to the main woofer, and the tweeter wires go to the tweeter. The crossover basically splits the signal into highs (for the tweeters) and lows (for the woofers).
