I'll second. Looks good to me.
Are you doing a 1 piece pan or 2 halves? If it's 2, leave half the tunnel as a reference.....
For bracing there is no such thing as ugly, it just all functional. As for your pan panels there is one thing that has been over looked, the rear most section is stamped to match the floor in the back or the smugglers box in the El Camino. I kept forgeting about that even when we were talking about where to order them from. One tip I'll add is just do one half at a time to add extra strenth & reduce any other factors that will allow ant flexing.
Now is the best time for something like that....Did someone say flat floor for subwoofer wall?
Is there an audio joke here that I'm not getting?
