Picked up this sub at a garage sale and it sounds pretty good in the box its in now but for how large this sub is I think its still small. What did these subs call for or what makes them work well? How much power am I going to need for it? Im running it in I think a 1 cf box on a ZR360 at 2 ohms really loud now but the guy I bought it from said it will handle like 1200 watt so I think Im going to need a bigger amp.
