Inline fuse for our amp, necessary with battery in trunk?

I had my system hooked up by a professional with the same car as mine. When installing my 5 channel amp, he did not use an inline fuse on the 4awg power line (even though the Rockford Fosgate amp came with one included).

This was 3-4 years ago. I recently discovered this when my RF amp unmounted, fell on its face, and burned alive. I hooked up my new Alpine amp using the same power, ground, and leads from the professional install and have not had any problems yet.

Should I even bother putting an inline fuse into the wiring now? It went so many years without an issue. I read that an inline fuse is very important, but I have also read that the chance of our E46 trunk batteries/power leads short circuiting due to an accident is nil.

I'd appreciate some honest advice from anyone who has been in the same situation as me.

Thank you all.
