• wherein the internal cavity provides a resonation chamber for the speaker;
• a port formed through the second vehicle body panel to port the resonation chamber;
• wherein the port is vented externally of the interior of the first vehicle body panel;
• an insert vehicle body panel extending between the first vehicle body panel and the second vehicle body panel to enclose a region of the internal cavity, wherein the insert vehicle body panel reduces a volume of the resonation chamber to tune the resonation chamber to the speaker;
• and
