powering two subs with a mono channel amp

yes if you wire it that way you will have 500 watts rms to ech sub. 

if you hook 2 voice coils that are 4 ohm as + to + and - to -   that will give you a 2 ohm load if you take 2   4ohm voice coils run one + to the other voice coils - then the remaining + and -  to your amp it will be a 8ohm load

ok you have a PM

i know im not the best at explaing this stuff by typing it but you have a PM check it

hey i forgot to tell you while we was on the phone but you only need a kicker ZX750 to run thos subs a zx1000 will be to much. so if you do use a 1000 be carfull because it will be to much power.
