Okay, I have just got two pioneer 12" subs, wired in the box, and a 150W Punch amp for christmas. Today I bought the wires, fosgates, and need to still buy a good cd stereo. What would be a good buy? I am looking for something not too much more than 100 bucks...also, what is the difference between having one or two preouts? Does it make a difference? Should I get another amp to help power my subs? If so, should i also get a power cap so the juice from my battery wont be totally consumed by my stereo? Any help is better than the little knowledge I already have...thanks...
