With a budget under 1200, I'd look at brands besides JL, they are very expensive. You can get better products for less.
Subs - Adire Shiva, Elemental Designs K series
Amps - JBL, US Acoustics, SoundStream
Maybe something like two ED K's and a JBL 1200.1 = would run you around 600, so youd still have 600 to spend on other areas of the system, and it would pound a lot harder than the JL setup youre thinking of getting. What are you looking for in terms of SQ/SPL?
