Above are the tools we used to install our sound system. We forgot to include in this picture the coat hanger and liquid soap. Do not use dawn as it is a very strong cleaner and could damage the insulation. Drill and Drill bits Small metric socket set Phillips and flat head screwdrivers Good set of crimpers good and inexspensive pair shown Allen wrench set Duct tape and masking tape Utility knife Marker 5/16 inch driver for self tapping screws - note the extension. Optional tools you saw during our install: Body panel remove (plastic). Not really necessary but helps. Fancy wire stripper (next to razor above). Kind of a cool tool
