I wanted to upgrade the standard door speakers without altering the door panels.
Finding same size units is not a problem but most are a four fixing job, Micra speakers are a three fixing design.
The speakers I bought had multi holes tor different mountings but however I rotated them not more than one hole would ever line up. The easiest solution was to fit the new speaker using the top hole in the door and centralising the speaker before drilling two small bottom holes. The original bolts/screws are self tapping so tighten up as well as before.
With the door card back on no one would visually know so theft factor reduced but benefitting from extra music power.
