i needed to make something simple to house my amps and wires in the trunk so i built this little rack today. it will sit between the box and the rear seats, amps facing forward. i have a question about the sides though. i wanted to leave them as open as possible for airflow. i was thinking about covering the open sides in speaker grille cloth to allow air movement but wrap the rest of the box in the typical charcol gray carpeting. any thoughts or suggestions?
