I have a couple 6x8 3 way's up front. Had to cut the tin a little bit to get them to fit. I had a couple 6" speakers in the back next to the seats too, but they just got in the way and I couldn't hear them over the wind noise when the top was down (80%) of the time here in San Diego. I did put in a 10 inch sub behind the rear seat. Had to custom build the sub box because it's a weird shape space to fill and I needed to optimize the whole area for a sub that size. There's space for an amp if you bolt it up just under the glove box. There should also be a wire you can tap into for your radio's 12-volt battery lead. It goes to the optional in-dash clock. Mine didn't have a clock, but the connector was there. Just use a meter to find which wire is hot.
edit: just noticed you have something large in your package tray already that would prevent you from sticking an amp under there.
