The SQC (Sound Quality Challenge) format is judged and scored on Sound Quality only and is designed for those who focus on the sound quality of their vehicle, not necessarily the level of detail in the installation.
There are two Classes in SQC; single seat and two seat. This means that in the "single seat" there is only one judge evaluating the system sound from the driver's position and two judges in the left and right front seats in the "two seats". The single seat Class is designed for competitors in the Rookie, Amateur and Pro Classes, while the 2 seat Class is open to all Classes. Scoring is based on the IASCA judging criteria of; Tonal Accuracy, Sound Stage, Imaging, Sound Linearity, and Absence of Noise.
SQC is judged with the Official IASCA Sound Quality Reference CD, using the traditional IASCA Sound Quality score sheet.
