If small foot print is what you are looking for why dont you look into a 4 channel 200-280RMS It would probably take up less space.
If 2 channel is what you are set on then model year 2000ish rockford fosgate punch 160a2 amps are small if you dont mount the pretty covers. They run 2x40rms @4ohms and that is underated. I was running two 10s off it at 2ohms and it was putting out more power than I liked (too rice sounding) I had to crank the gain down.
RF are nice, I used to be all about RF and Alpine, well I still am. Recently I got a sony amp just cause it was cheap and to my suprise it actually works very well. Better than my Kenwood and Pioneer ever wood be. If you got the money go for the RF, but if not, try Sony. You can get them at Sears and if there is anything wrong with them down the road, you can get them replaced for free, no Q's asked.
If your looking for the smallest footprint amp you can get at a reasonable price, check out the Blaupunkt amps. The T Class amp is a very high quality and physicaly smalll unit. They also run cool so they can be mounted in more locations without the threat of overheating. They have 2 and 4 channel models but the 4 channel seems to be the hard one to locate. Crutchfield carries their 2 channels.
They come on a plastic 'body' sort of which can be removed. The amp itself is very small.
Lanzar also has some small amps but the price is up there.
Audiobahn also has some very nice, very high power units available in a nice price range, espically for their performance, though they are harder to find lately...
If you can't take a nano-second to press shift/period/etc. and make proper sentences and paragraphs, I don't know if I can take a few minutes to respond to your topics... It doesn't have to be perfect by any means, but a little effort goes a long way.
