This setup really freed up trunk space on my daily driver. Fit was perfect on a 18 Civic LX sedan, Color match was pretty good. This box was installed with a Punch P3 D2 12 and I had added on a Punch grill for protection and was choosy with a Stinger Audio MT700.1 amp so I didn't have to upgrade my alternator. This setup shakes the mirrors and the sound is really good being a sealed box but the bass is not too extreme. The bass shakes your hair but not your teeth like when I used the same setup on a 0.95 cu/ft downfiring ported sub box. The only things that had to be modified was I used a nice sized stainless screw to mount the top of the box to the car and the wiring inside the box was too short since the Sub I had added had a really beefy magnet and a dual voice coil. Hope this helps others.
