A Kicker
A kicker is a sub-woofer, but not just any sub-woofer, it’s the kind that makes your car vibrate so hard it feels like it’s trying to escape your body.
I had a kicker in my car. It was so loud, my neighbor called the cops. That was a kicker.
My cousin’s kicker was so loud, it woke up the whole neighborhood. That was a kicker.
My friend’s kicker was so loud, it made my dog howl. That was a kicker.
