Hey thanks for the pointers...So I have been thinking and since I may want to move these to my new car in the summer, I am probably going to get 2 Rockford Fosgate Punch 12" Car Subwoofer (P112S4).

Now I was wondering if anyone had any experience with the comparision betwee 2 10's vs. a single 12. How noticeable is the difference. I'm pretty sure that the 2 12's will be game enough though.

Any suggestions on what amp to pair with these subs?

Many thanks

p.s. if anyone could direct me to some basic articles on amps and car audio in general that would be much appreciated.
