Help Me and a Buddy With Sub & Amp Selection

I don't get this stuff but we are trying to build my buddy a good system for his 05 Colorado i know i know....

But we are going with this line of Rockford Fosgate Subs. We need the shallowest mounting depth possible and an amp to efficiently power them. I just don't know a thing about Ohms or Channels or ANYTHING!

Out of these http://www.rockfordfosgate.com/products/product_selector.aspx?catid=31&parid=4 (they need to be 10") which is the best and whats the best amp to power them?

Thank You So Much For Your Help!!!!!

I'm thinking a mono amp is the best choice

 

You seem to be going in the right direction. Mr. Marv would be a good place to start if you need any help. He has helped me through the last 4 set-ups. Be sure to watch yourself on sonic electronix. I have had bad dealings with them in the past on more than one occasion.

 

Jeremy,
Alpine is probably your best choice. Make sure you get a single channel amp. There are many others out there but I have an Alpine V12 expert that's over 10 years old and has been in three different vehicles and still kicks a@@.
