Default power rating for stock radio?

I just got my car and the stereo is pretty crappy as most of you now if you are in the stereo portion of the forum. What my plans are, is use the Infinity Kappa 63.9's (3 way 6.5') in my doors. Infinity Kappa 692.5's (old model 2 way 6x9's) in a trapiziod shaped boxes placed in the trunk. I am undecided on if I want to save space by placing them infront of the strut towers or not screaming in my ears and place them in the back of the trunk facing toward the hatch. I also have a IDQ 12" sub in a .8' box w/ MB quarts discus 600watt RMS (it is a little over kill but it was the right price and the IDQ's are way under rated + my gain is turned down). I will leave the stock tweeters unless they just shound horrible with the rest of my system then I will get order some Infinity tweeters. I will cross that bridge when I get there.

I have an Avionixx 440.4 amp 85rmsx4 for my surrounds should be perfect for that I have. I was building this system for another car but the motor died so I got my new one. I just looked and my amp doesn't have high level in puts. The high to low input convertor I am looking at says it is rated for not more than 15watts. Is there much difference in $5 and $50 ones other than fancy packaging. I am going to hide it as much as possible. I just want it to work.

I also am not sure how I will set the sub in. The box is just a cube. 14.5 or 15" X 14.5 or 15" X 8". I can't remember, but it is in that neighborhood. The amp is mount on the back with the sub facing down. The old car had a roll cage that the front rested with the sides being held up but the 6x9 boxes mentioned above. What would be a decent way to mount in the car? I am kinda nervous to take the amp off since I screwed it on to it. I don't want to unseal the box. Kinda tall to set in its an edge. It I fix legs to it or 1-2 in blocks. I hate to put holes in my new car. Do you think Velco is strong enough to keep it form sliding around the truck?

Sorry for the novel and thanks for any input.
