These are great 2 way bass response speakers, I have installed them in the rear doors of my wagon and I am so happy with the combined sound of my 2din head unit & 4 speaker set up that I am no longer looking for a sub woofer.
The speakers are garbage too quiet no bass distort at 75% volume spend an extra 30 bux and get Rockford Fosgate R1675X2. The difference is chalk and cheese.
