Day after my brother got his one subwoofer in a ported box, he took me for a spin, put in nelly, and boom boom boom. I was like WOWA this thing is loud, thought it was awesome....moved on to the rest of my day. But it didnt stop there for my mom, no, she went and got better (yet same size) sub in a ported box, with more watts pushing it then what my brother had. The day shes supposed to go get it hooked up, I needed to go get some new shoes. So we drive into town and shes like I got a surprise, pulls into the audio shop where we have to leave the car for an hour. So Im like ya ok w/e and we go get supper, come back, and BOOM BOOM BOOM, wowa! I thought it was great. Since then I've been helping her with stuff in her system, planning some stuff out that should hopefully happen soon.... and now I know more about audio and the non-audible spectrum. INFRABASS BABY!
-P.S. thanks mom
