I moved them around a little, but was limited to space because i needed a place for the amps. I thought about turning them around and sealing it off (a wall facing inwards) seeing if that would help. I know i can hit louder DB ratings with them as my friend had 2 and hit 146.7. The box was built so i could be taken out of the trunk. I'll have to find my measurement papers to tell you the specifications.
