Mounting: The ST9MR midrange drivers are designed to mount in free-air applications. They are just over 3½" deep (3.57") and require a square opening approximately 7¾" x 7¾".
Terminals: The spring post terminals accept wire up to 12-gauge. Kicker recommends using at least 16-gauge wire (minimum).
Crossover: These speakers do not include a crossover, so you'll need to add one to integrate them into your system.
