Stereo & Electronics - Rear speakers

Alright im looking to get a set of 4in componet speakers for the hatch area of my 99 trans am. I will be powering them by a Alpine pdx-f4 amp which runs at 100w rms x 4 @ 4 ohms.
Any suggestion on speakers that can hold that much power? I know that my rear speakers need to be my "fill" so I dont wana blowem up.

You can fit 5" speakers as long as the mounting depth is less than 50mm. You would have to mod the plastic tabs and make the hole slightly larger. I just did that for my car; even built an mdf support board/baffle and the results were very pleasing (not sure about the 100rms though but you could dial them down).

I might have some pics if your interested in my install.

Cheers.
