help wiring

hi i have a kicker kx600.1 mono amp and im trying to wire my subs. I have 4 12 inch compvrs .. i only plan to use 2 at a time but i messed up and both both so now i have options (2 ohm and 4 ohm models.. 2 of each) i guess.. but anyways. Which would be best subs to use and how would i wire it.. i thought i have it wired right cuz im using the 2 2ohm models right now and used those crutchfield wiring diagrams to wire it to a 2 ohm load but it keeps going into protect or blowing the fuse.. help..

your best bet is using the 2 ohm and wire it up like you had it butt you have to set the amp you no the gain and bass boost same thing was happenig to me

how should i set the gain an the bass boost to get the best performance without making it blow the fuse or go into protect.. and what does the sub sonic thing do

not sure about the sonic thing but how i always set mine is set your cd player on the settings you usully listen to it on (volume, bass, treb., etc.) then set your gain and bass (turn gain a little then bass and repeat) tell you think it sounds good and its not going to protect now if your fuse pops may be its to small it shouldnt be poping like that though do this and get back to me with concern,problems.
