I think my sub hits pretty hard for what it is. The front speakers are like the stock ones thats why i wanted to hook them up to an amp and i also have the 2 6x9's in the back other than that evreything is stock. i got a box that looks like a trapazoid non ported the wiring kit the amp and the sub for 15 bucks so i aint *****ing. its kinda funny because all of the kids at my school have like p3's and p2's and spend like 1000 to get them installed i just laugh at them because it only takes about an hour to wire a car for subs. and i only paid 15 for my whole set up lol.
