New at installing Subs

i have a 98 dodge neon and im going to be putting my system in this week or next. i pretty much have the amp part down im mainly confused on how to wire my subs inside the box and to the amp. i have 2 infinity 1242w subs and a boss audio rt645  amp. my friend had me buy monster audio speaker wire from radio shack to wire the subs to the terminals on the box and then from there to the amp. i never did this before but the speaker wire doesn't have connectors on the end its just open wire. do i just plug that into where the connector would go or do i have to do some thing else. also which wiring diagram should i use the dual voice coil 4ohm one ? if so can some one explain it a little bit so i know what exactly im looking at.

thanks for any help you can give.
