Reply to Young DJ looking for reasonably priced PA system with good low end

Hi,

I just turned 18 and am doing a lot of house parties / small club gigs. I play mostly house, dubstep, trap, and hip hop. I don't have a huge income, but I'm looking to get a system that'll really thump in a house party scenario. The only thing is I don't want to worry about blowing it out because I crank it, and the main reason I would do that is because there isn't enough bass. I don't know if this is unrealistic, but maybe you guys could point me in the right direction? I'm just a spring chicken and don't know exactly what I'm doing, but I want to throw really awesome parties. Can someone help me out?

EDIT: I just want to point out, most of my music is pretty much useless without good low end. The build up can sound really epic, but when it finally drops it just disappoints. I have a Mackie Thump TH-12 but I believe I blew it out from my birthday party... So would the TH-15 be a better option, or should I ditch Mackie altogether?
