Whats up fellas.... I had this box made for me but in the process went in another direction & decided to sell it. This box is brand new & was cusom made for a g35 coupe. With the 10w7 installed it is exactly 1.25 cubic ft. for optimal performance. All u need is the 10w7, & a jl 500/1 amp & you are in business. I want to sell this locally to avoid shipping charges. I paid 375 for this & will part it away for 350 (firm). Like I said this is brand new, never used & is one of a kind. Pics were taken to show how it fits inside the trunk of the coupe.Pm me for additional info. thanks...
