How do you hook up a crossover to the amp?

To hook up a crossover to an amplifier, first, connect the output from the amplifier to the input terminals of the crossover using speaker wire. Then, connect the crossover's output terminals to the appropriate speakers, ensuring that the connections correspond to the correct frequency ranges (e.g., high-pass for tweeters, low-pass for woofers). Finally, ensure all connections are secure and double-check the polarity to avoid phase issues.
