those look fine, are you using a custom box for these or are they just in a regular box? usually from what ive seen is you have to splice the new radio head into your car, then plug in your audio cables from the sub into the back of the new radio and re-install that. then connect your amp to your battery and ground it. then connect your audio cables from your radio head to your amp and connect subs. install fuses and baddah bing botta boom, adjust gain, and tune subs. bump dubstep!
just remember to label or know every wire you disconnect from the radio. thats usually what takes the most time. installing the new radio and wiring from battery to amp,
