Okay, it's obvious you need some help and most people replying aren't thinking of when they were new to this. Buy the subs if they work. That is a hell of a deal on them. Buy the amp kit as long as there is enough cable for your vehicle. That is also a deal. With the amp, get something cheap and between 1000-1500 watts @ 2 ohms. You are new to this and you WILL fuck up some equipment. Learn on the cheap stuff. You can spend $300 on an amp and break it, or you can spend $500+ and break it and pay for repair costs because chances are you are going to damage it by something not covered under warranty. Take your time, doublecheck everything, and gain as much knowledge as you can. Just remember, when it comes to the internet, there is as much misinformation out there as there is quality information.
