So, what did you do?
I just took the cups off of mine this weekend. I figured, why hide the Eclipse Point Source 6X9's since the look kinda cool with the clear crossover network mounted to the side of the magnet housing.
The speakers look cool, but the overall effect is that the trunk looks more cluttered, especially since my entry-level (if that) gear is all up against the back of the seat (an 8 inch powered sub in a rectangular, ported enclosure centered and strapped on the "shelf" with a small amp mounted to the seat-back on one side and a distrubution block mounted to the seat back on the other side.)
I'll give it a few days, but I may put the foam back on.
