Sub / Amp Compatibility Question

Hi everyone,

I have a Kicker ZX750.1 that I had from years ago (fingers crossed it still works) and am looking at adding an 8 inch sub to my Chevy Colorado Extended Cab (fits in-between the back seats nicely).

I found a person on Ebay who sells a 2 ohm DVC sub and a 4 ohm DVC sub.

Am I correct in thinking that I'll need the 2ohm DVC version? If the subs max power handling is 450 watts, is the 375 watts RMS of the sub too low?

Thanks a ton for the help!
