i have a 2007 subaru impreza. i wanna install comps, a 12" sub, two amps and a preamp.. my question is can my stock cd deck work. i have not taken it out but do anyone know if it have preamp outputs? if it can work will running an external 3-way crossover help the sound?

You will need converters

You can buy a processor (IIRC, Pioneer makes one, and so does JL) that turns your speaker signals into RCA signals. They might have 3-way X-over on these processors, I'm not sure. IIRC, they're about $80 bucks.
Or you can go to a local audio shop and get a 'Hi-Low converter' which is a smaller version for about $20 bucks.

i rocked a high low converter for sum time with my stock hu. if you have the money upgrade to a nice HU. trust! SQ is way better on a hU with a sub pre-out! but yeah u can hook up amps to a stock cd deck.

Does it really make a difference in SQ between a Aftermarket HU and a Stock HU cause I thought the Rca's were just for a signal.

it did for me. and its not because i thought the stock HU ****** its just that with the High low converter the subs didnt respond as fast/ didnt hit crisp or clean. sounded a little muddy. Its also pretty hard to fine tweak a stock HU like an aftermarket one.
