yeah do that and at full volume when the car resonates at a different freq you score will suffer. don't lsiten to the guy who on 2 4k's and 2 9917's couldnt break a 53.....You should def be louder with the right tone. Have em do it again right. Sweep at low volume, find the peak, and play that tone. Then mess around with the interior, seats up, seats down, visors, etc.
