There is a lot of room there, but it wouldn't be that easy to get to if you need to make adjustments. I have both JBL Sirius pieces installed there. My Alpine PDX600 is one of the smaller amps on the market that is still able to push a 12" sub with 600 watts. There is no way that would fit behind the glove box with the other two Sirius components there.
The best options I see for mounting an amp is the hidden compartment, under a seat, or on the speaker box itself. I understand having the 3rd row seat limits the space. My suggestion is to take the Rav to a car audio place and get their recommendation on the best place for an amp based on your interior configuration. Just please don't take it into Best Buy or Circuit City. Take it to a real reputable car audio place.
