what would be better with 2 1500 watt (750 rms) kicker L7's... a ported or unported box? also, anyone know a good site that builds custom boxes? i have an 05 extended cab colorado and so far ive jsut been looking at regular boxes and i cant go any farther than 33 inches in width because im only gonna take out 1 back jump seat. and the depth of anything lower than 15 would be sweet so i can lean my seat back comfortably. i dont care about the heighth.
