how to wire two kicker s8l7's?

ok so her is what ive got goin on ive got two kicker s8l7's behind the seats of my regular cab 1999 s-10 right now its wired to a pioneer 1000 watt class D single channel amp

they are wired like this at the moment

ive got them wired just liek together well i mena i just put both the grounds from both subs, and the positives from both subs and just wired them strait to the amp. theres only one spot on the amp thats like spekaer out, so i plugged both subs into the same spot.. is this bad or is it alright? is there a differant way i should have these subs wired?

I believe those are dual 4-ohm voice coil subs, which when wired in parallel  creates a 2 ohm load each, or a 1 ohm load all together.  I'm not so sure you're amp is stable to 1 ohm or not (check your manual).  Most mono amps are stable to 2 ohms, but not necessarilly 1, so check to be certain. 

If your amp is not stable to 1 ohm, you can series the voice coils, and parallel the woofers, creating a 4 ohm load.  Otherwise, get rid of one woofer and just parallel the voice coils for a 2 ohm load.

alright well i changed the wiring to i think a 4ohm load.. well this is how its wired now

or well liek this

i guess i cant really tell if it sounds any differant or not.. is this  how u think i should have it wired or not?
