your subs will be really underpowered but you can run the two subs in series with each channel. meaning each sub will present the amp will a 2 ohm load, heres how to wire each sub to your amp

will it be underpowered because im using it to drive my front speakers or is my amp not that good? if i use this amp just for the subs would it be enough power and if so how do i wire it. i kinda had a feeling i needed a 2nd amp but right now this is gonna have to do.

thanks alot for responding

No no, wiring like Ketel22 shows above will give you an 8-ohm load. The diagram below shows how to get two dual 4-ohm drivers to a 4-ohm load on your amp. Wire like this to two bridged channels on your amp:
