I had a 10 inch kicker comp vr in a .7 cft prefab sealed box powered with 300w rms. It sounded all right..not bad at all. then i built a box for it..1.75 cubes tuned to 32hz..and wow! ..it gets as loud as my 12 inch cerwin...probably louder...makes me wonder what would happen if i built a better box for the cerwin. so i would say if its a decent sized box then you should be good, but if u have the time, build your own.
