What tools are needed for installation?

Basic tools like a drill (for flush-mount), screwdrivers, wire cutters, and a multimeter for checking connections.

Do I need to use the included capacitors?

Yes, the capacitors are required for proper crossover filtering to protect the tweeters from low frequencies.

What should I do if the tweeter produces no sound?
