I have a question a about car amps do you much about them

Depends... what's your question.

OK I want to know what is better to do, hook up two mono amps to 2 sub woofers and even if I can do that or if its better just to hook up the 2 subs to one 2 channel amp.

What kind of amps and what kind of subs are you looking to use? Also what are you going to use as a head unit? Finally, what is your desired output level (full sound, hear me a block away, hear me a 1/2 mile away).

for the subs I was thinking of pioneers 800 to 1200 watts, eather sony or pioneer amps, and I have a ultimate 55x4 and I want it to have a good sound full sound, not that crap raddal and reverb .
