id you get dual 4 ohm subs, you're only options are to either wire them both down to a 1 ohm, 4 ohm or 16 ohm load. with that amp, you would need to do a 4 ohm load. 16 is never applicable.


if you need help figuring out how to wire subs together and such use:
Subwoofer Wiring Diagrams, Two 4 ohm Dual Voice Coil (DVC) Speakers

 

These subs are dual voice coil 4 ohm so cant you wire them to 1 ohm, 2 ohm, 4 ohm, or 8 ohm? i thought i read something about that but i could have forgotten. ill take a look at that site too

Edit: just kidding i looked it up, only way to wire dual voice coil subs to 2 ohm is with a 2 channel amp.

 

to a final two ohm load, you would either need a 2 channel amp or 2 separate mono block amps.

1/(1/4 + 1/4) = 2 ohms
1/(1/4 + 1/4) = 2 ohms

1/(1/2 + 1/2) = 1 ohms final load


just throwing the math out there for if you want to figre it out later on your own
