Hey i have Two 10" Infinity Kappa Subs with 350 RMS power and 1400 peak power as it is right now I have a ZX 450.2 kicker amp on them and its just not working for me it doesnt hit hard at all so im thinking of upgrading the amp to a mono channel to get more power and Im wondering if I should do two seperate monos or one high powered mono i was told with a mono amp on two subs that it will cause the two subs to play as one consistent unit and not as two separate subs. Im thinking of putting a ZX1000.1 kicker amp instead of the 450.2? what suggestions does anyone have

What voice coils are on the subs? The kicker 1000.1 is a beast so that might even be over kill on those subs

Option 2 (series/parallel) = 2 ohm load
Voice coils wired in series, speakers wired in parallel
Recommended Amplifier: Stable at 2 or 1 ohm mono

ohms is resistence. 4ohm has more resistence then 2ohm and 1 ohm has less resistence then 2 ohms. with your kicker amp it probly only 2 ohm stable so running a 2 ohm load on the amp will get the most power out of your kicker amp. if you ran a 4ohm load on the amp insted of 2 you will loose about 1/2 the power it can put out.

Ohms also determines how long your amplifier will survive.  Your amp is 2 ohm mono stable.  You really need to follow the diagram I posted.  If it makes you feel any better, each speaker is wired as a 4 ohm speaker.
