Audio Systems: Two 10 Subs, exact model number, rms power

Question
Hi, I just purchased two 10" Pyle 600 watt each subs off of ebay.  1.5" High Temperature Kapton Voice Coil. I was just wondering what type of amp I would need to get a decent quality sound out of these. I will be wiring it into my factory stereo in my 2005 GMC Canyon. Any advice on how I should go about do this? I'm planning on building a box (since I'm a carpenter) and putting it behind my seat. Thanks for your help.  

Answer
I can give you a ton of great advice but I need more info 1st.
If you want to re-submit this using the 'private question' option and let me know the EXACT model number on the speakers, I can help you out.
I am sure they are probably 300 watt RMS each (continuous power). I am guessing that they are 4 ohm (If so, I will let you know that it is best to buy a pair of 8 ohm ones in most cases for subs since to get the best performance out of them you will need to send near RMS power across each speaker... more on the 'why' when you resubmit).
