Hey, i've had a box built for my vega 12 single 4ohm sub at the audio store. It was built to manufacturer's specs, but i've heard a car with the same sub with same power, n it sounds almost twice as loud. The box is a larger ported box though. I dont know if anyone in here has specs better than the manufacturer's box specs. Please share, i'll be grateful.
