Does this look like a decent set up?
 

Hey guys, I'm definitely no expert on car audio but have been putting in some serious research the past couple weeks as I have been trying to piece together a new audio system for my ford focus. I've put together a system and was hoping I could get some feedback (Feel free to call me an idiot). Thanks

Do you plan to build an enclosure for the woofer? Or did you just forget about it? :P

Double post

You linked to a DVC 2ohm Type R, you should get the DVC 4ohm instead.
Have you looked in the BST here? You can get some nicer stuff for cheaper.
