Nope, it is not deep enough for a another full size unit. However, it will fit an EQ if the processor is a separate unit kind of like a A/V receiver module. Best example, is the pioneer EQ's. Their EQ faces are only about 2.5 inches deep with a wire connecting to the processor (brain). But you'll have to fabricate a radio dash kit for the entire opening. Hope that help ya and not confused ya.
