Not in that spot. It's like 24" high, and each amp is 10". There is ~29" (memory, I could be way off) of useable space wide, so if you really worked it you might be able to squeeze 3 horizontally. I figure I'll keep the sub amp in the seat back to keep the big heat generators (or amps that see the most use while sitting) far apart. Since the Harpoon will likely see less use I'm going to put it next to the 800.4 on the side wall.
