What kind of wiring kit should i use for my amp in my car?

Cheapest and best way is go to Wal-Mart and they carry amp install kits for 600W or less amps. Other than that everything looks alright. You really need a little more amp for those speakers but it'll most likely do the job... I guess you aren't going to use the head unit hookups, unless you have some tweaters you are planning on using, that you didn't mention...
