Hi! Was wondering if the compartments in the rear cowl have been used for sub mounts; I would like to use the stock speaker holes w/ the orig. covers and install quality speakers/size?? These don't look like 6x9s. Are the a 5" spaeker? The whole sys. was gone when I aquired the car. What would the ideal trunk sys be including a mild sub and speaker sys while retaining the orig look? Can you remove the door flaps where the 1st aid kit was and storage compartment and put a sub under? what would be a sensible approach? Tanks les
