I had this sub for about 3 months now and its a great attribute to my system. I'm running 4x6 Infinity References, 6 1/2 Infinity References in the back, and a Pioneer Premier head unit in my Nissan 240sx Coupe. The sub is not designed to make car alarms go off, or make your heart skip a beat, but for its size, it packs a good punch and will hit all the notes really well. This will also save a lot of room in your trunk if space is a concern. If your a bass head, this isn't for you, but if you like to have your music clear and just right, look no further.
