help wiring subs

can someone give me advise on how to wire my subs.

i have two diamond audio M6-10D4, 500 watts,ohm dual 4 (this is were im confused i never saw subs with 2 sets of speaker terminals)  and a rockford forsgate 4 channel amp #501x. specs are 65 watts x 4 @4 ohms, 125 watts x 4 @2 ohms, 250 watts x 2 @4 ohms bridged. im also using this amp to power my front speakers.im really not sure how to go about it so if anyone can help i would appreciate it.

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

i would advise getting a seperate amp for you sub because of power issues

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:
