yes, just look underneath the inner side of the center dashboard below the steering left side.
usually if require a spacer your installer will do it for you otherwise is just screw on to the metal door frame. Window gets stuck or not is best using a spacer or depending on the thickness of the speaker magnet. Given that your installer can easily kaotim!

you can always try to diy & is advisable to use spacer due it can double up act as an anti-vibration absorbent zone against metal surfaces, speaker & door as well as avoiding the knocking of the glass window winding up & down!
you need to unclip all the front under bumper part cover to access to the foglamp, lying down face upright! But if you wanted to addon foglamp to the non-foglamp bumper then need to unclip a few from the front wheelarch, unclip the under cover & unclip the top bumper holding parts with unskru 3 main screws from the front grille to take off the whole bumper! whish do you prefer?
