With the included ceramic resistors, you can fine-tune the power distribution and prevent overloading the horns. And let me tell you, it makes a noticeable difference in the sound quality.

Installation was a breeze thanks to the provided components like wiring harnesses and mounting adapters. And once they were installed, I was blown away by the power handling capacity these speakers have.
