Dude your budget is perfect to buy my Basically new, Audioque HDC315, there isnt a scuff on it. Its a 15, DVC 2 ohm and will get pretty much louder than most out there. Lemme know!Couple good subs with nice bass. spending about 100-200 depending on model. then i'll need amp to power those subs. 600 700 800 watt amp something like that
