Someone told me that jl audio makes a stealthbox sub for the 2003-06 Cayenne, but when I contacted my cousin for same he said it would not fit in my ’09 GTS. I can’t figure out why this would be the case. Aren’t the interior components still the same? When I download the installation instructions, it appears that all the interior panels, trim, etc., in the trunk area are the same between gen 1 and gen 2 Cayennes? Even my cousin have no reason so can anyone give me reason tht why is it so?
