Help me out!

Ok im looking to build my system up slowly. I already have a good foundation with two infiniti speakers(its a pickup truck) and a pioneer headunit. Hte headunit is almost the top of the line i thinks its number is 8600. The next logical step is an amp right? From what Ive heared Adiobhan is a good brand for amps, is it? And then subs which im thinking of going with two rockford fosgate 10s. What do u guys think?

Check them out, they have awesome stuff, great quality, and is really cheap. I'm guessing you dont have much room to work with for the sub(s) do you? What's your price range?

500 for whole setup
